 # Breaking Changes
 
-## 0.8.0
-
-- **Default to Python 3.9**
-
-    Ruff now defaults to Python 3.9 instead of 3.8 if no explicit Python version is configured using [`ruff.target-version`](https://docs.astral.sh/ruff/settings/#target-version) or [`project.requires-python`](https://packaging.python.org/en/latest/guides/writing-pyproject-toml/#python-requires) ([#13896](https://github.com/astral-sh/ruff/pull/13896))
-
-- **Changed location of `pydoclint` diagnostics**
-
-    [`pydoclint`](https://docs.astral.sh/ruff/rules/#pydoclint-doc) diagnostics now point to the first-line of the problematic docstring. Previously, this was not the case.
-
-    If you've opted into these preview rules but have them suppressed using
-    [`noqa`](https://docs.astral.sh/ruff/linter/#error-suppression) comments in
-    some places, this change may mean that you need to move the `noqa` suppression
-    comments. Most users should be unaffected by this change.
-
-- **Use XDG (i.e. `~/.local/bin`) instead of the Cargo home directory in the standalone installer**
-
-    Previously, Ruff's installer used `$CARGO_HOME` or `~/.cargo/bin` for its target install directory. Now, Ruff will be installed into `$XDG_BIN_HOME`, `$XDG_DATA_HOME/../bin`, or `~/.local/bin` (in that order).
-
-    This change is only relevant to users of the standalone Ruff installer (using the shell or PowerShell script). If you installed Ruff using uv or pip, you should be unaffected.
-
-- **Changes to the line width calculation**
-
-    Ruff now uses a new version of the [unicode-width](https://github.com/unicode-rs/unicode-width) Rust crate to calculate the line width. In very rare cases, this may lead to lines containing Unicode characters being reformatted, or being considered too long when they were not before ([`E501`](https://docs.astral.sh/ruff/rules/line-too-long/)).
-
-## 0.7.0
-
-- The pytest rules `PT001` and `PT023` now default to omitting the decorator parentheses when there are no arguments
-    ([#12838](https://github.com/astral-sh/ruff/pull/12838), [#13292](https://github.com/astral-sh/ruff/pull/13292)).
-    This was a change that we attempted to make in Ruff v0.6.0, but only partially made due to an error on our part.
-    See the [blog post](https://astral.sh/blog/ruff-v0.7.0) for more details.
-- The `useless-try-except` rule (in our `tryceratops` category) has been recoded from `TRY302` to
-    `TRY203` ([#13502](https://github.com/astral-sh/ruff/pull/13502)). This ensures Ruff's code is consistent with
-    the same rule in the [`tryceratops`](https://github.com/guilatrova/tryceratops) linter.
-- The `lint.allow-unused-imports` setting has been removed ([#13677](https://github.com/astral-sh/ruff/pull/13677)). Use
-    [`lint.pyflakes.allow-unused-imports`](https://docs.astral.sh/ruff/settings/#lint_pyflakes_allowed-unused-imports)
-    instead.
-
-## 0.6.0
-
-- Detect imports in `src` layouts by default for `isort` rules ([#12848](https://github.com/astral-sh/ruff/pull/12848))
-
-- The pytest rules `PT001` and `PT023` now default to omitting the decorator parentheses when there are no arguments ([#12838](https://github.com/astral-sh/ruff/pull/12838)).
-
-- Lint and format Jupyter Notebook by default ([#12878](https://github.com/astral-sh/ruff/pull/12878)).
-
-    You can disable specific rules for notebooks using [`per-file-ignores`](https://docs.astral.sh/ruff/settings/#lint_per-file-ignores):
-
-    ```toml
-    [tool.ruff.lint.per-file-ignores]
-    "*.ipynb" = ["E501"] # disable line-too-long in notebooks
-    ```
-
-    If you'd prefer to either only lint or only format Jupyter Notebook files, you can use the
-    section-specific `exclude` option to do so. For example, the following would only lint Jupyter
-    Notebook files and not format them:
-
-    ```toml
-    [tool.ruff.format]
-    exclude = ["*.ipynb"]
-    ```
-
-    And, conversely, the following would only format Jupyter Notebook files and not lint them:
-
-    ```toml
-    [tool.ruff.lint]
-    exclude = ["*.ipynb"]
-    ```
-
-    You can completely disable Jupyter Notebook support by updating the [`extend-exclude`](https://docs.astral.sh/ruff/settings/#extend-exclude) setting:
-
-    ```toml
-    [tool.ruff]
-    extend-exclude = ["*.ipynb"]
-    ```
-
-## 0.5.0
-
-- Follow the XDG specification to discover user-level configurations on macOS (same as on other Unix platforms)
-- Selecting `ALL` now excludes deprecated rules
-- The released archives now include an extra level of nesting, which can be removed with `--strip-components=1` when untarring.
-- The release artifact's file name no longer includes the version tag. This enables users to install via `/latest` URLs on GitHub.
-
-## 0.3.0
-
-### Ruff 2024.2 style
-
-The formatter now formats code according to the Ruff 2024.2 style guide. Read the [changelog](./CHANGELOG.md#030) for a detailed list of stabilized style changes.
-
-### `isort`: Use one blank line after imports in typing stub files ([#9971](https://github.com/astral-sh/ruff/pull/9971))
-
-Previously, Ruff used one or two blank lines (or the number configured by `isort.lines-after-imports`) after imports in typing stub files (`.pyi` files).
-The [typing style guide for stubs](https://typing.readthedocs.io/en/latest/source/stubs.html#style-guide) recommends using at most 1 blank line for grouping.
-As of this release, `isort` now always uses one blank line after imports in stub files, the same as the formatter.
-
-### `build` is no longer excluded by default ([#10093](https://github.com/astral-sh/ruff/pull/10093))
-
-Ruff maintains a list of directories and files that are excluded by default. This list now consists of the following patterns:
-
-- `.bzr`
-- `.direnv`
-- `.eggs`
-- `.git`
-- `.git-rewrite`
-- `.hg`
-- `.ipynb_checkpoints`
-- `.mypy_cache`
-- `.nox`
-- `.pants.d`
-- `.pyenv`
-- `.pytest_cache`
-- `.pytype`
-- `.ruff_cache`
-- `.svn`
-- `.tox`
-- `.venv`
-- `.vscode`
-- `__pypackages__`
-- `_build`
-- `buck-out`
-- `dist`
-- `node_modules`
-- `site-packages`
-- `venv`
-
-Previously, the `build` directory was included in this list. However, the `build` directory tends to be a not-unpopular directory
-name, and excluding it by default caused confusion. Ruff now no longer excludes `build` except if it is excluded by a `.gitignore` file
-or because it is listed in `extend-exclude`.
-
-### `--format` is no longer a valid `rule` or `linter` command option
-
-Previously, `ruff rule` and `ruff linter` accepted the `--format <FORMAT>` option as an alias for `--output-format`. Ruff no longer
-supports this alias. Please use `ruff rule --output-format <FORMAT>` and `ruff linter --output-format <FORMAT>` instead.
-
-## 0.1.9
-
-### `site-packages` is now excluded by default ([#5513](https://github.com/astral-sh/ruff/pull/5513))
-
-Ruff maintains a list of default exclusions, which now consists of the following patterns:
-
-- `.bzr`
-- `.direnv`
-- `.eggs`
-- `.git-rewrite`
-- `.git`
-- `.hg`
-- `.ipynb_checkpoints`
-- `.mypy_cache`
-- `.nox`
-- `.pants.d`

-## 0.1.0
-
-### The deprecated `format` setting has been removed
-
-Ruff previously used the `format` setting, `--format` CLI option, and `RUFF_FORMAT` environment variable to
-configure the output format of the CLI. This usage was deprecated in `v0.0.291` — the `format` setting is now used
-to control Ruff's code formatting. As of this release:
-
-- The `format` setting cannot be used to configure the output format, use `output-format` instead
-- The `RUFF_FORMAT` environment variable is ignored, use `RUFF_OUTPUT_FORMAT` instead
-- The `--format` option has been removed from `ruff check`, use `--output-format` instead
-
-### Unsafe fixes are not applied by default ([#7769](https://github.com/astral-sh/ruff/pull/7769))
-
-Ruff labels fixes as "safe" and "unsafe". The meaning and intent of your code will be retained when applying safe
-fixes, but the meaning could be changed when applying unsafe fixes. Previously, unsafe fixes were always displayed
-and applied when fixing was enabled. Now, unsafe fixes are hidden by default and not applied. The `--unsafe-fixes`
-flag or `unsafe-fixes` configuration option can be used to enable unsafe fixes.
-
-See the [docs](https://docs.astral.sh/ruff/configuration/#fix-safety) for details.
-
-### Remove formatter-conflicting rules from the default rule set ([#7900](https://github.com/astral-sh/ruff/pull/7900))
-
-Previously, Ruff enabled all implemented rules in Pycodestyle (`E`) by default. Ruff now only includes the
-Pycodestyle prefixes `E4`, `E7`, and `E9` to exclude rules that conflict with automatic formatters. Consequently,
-the stable rule set no longer includes `line-too-long` (`E501`) and `mixed-spaces-and-tabs` (`E101`). Other
-excluded Pycodestyle rules include whitespace enforcement in `E1` and `E2`; these rules are currently in preview, and are already omitted by default.
-
-This change only affects those using Ruff under its default rule set. Users that include `E` in their `select` will experience no change in behavior.
-
-## 0.0.288
-
-### Remove support for emoji identifiers ([#7212](https://github.com/astral-sh/ruff/pull/7212))
-
-Previously, Ruff supported the non-standard compliant emoji identifiers e.g. `📦 = 1`.
-We decided to remove this non-standard language extension, and Ruff now reports syntax errors for emoji identifiers in your code, the same as CPython.
-
-### Improved GitLab fingerprints ([#7203](https://github.com/astral-sh/ruff/pull/7203))
-
-GitLab uses fingerprints to identify new, existing, or fixed violations. Previously, Ruff included the violation's position in the fingerprint. Using the location has the downside that changing any code before the violation causes the fingerprint to change, resulting in GitLab reporting one fixed and one new violation even though it is a pre-existing violation.
-
-Ruff now uses a more stable location-agnostic fingerprint to minimize that existing violations incorrectly get marked as fixed and re-reported as new violations.
-
-Expect GitLab to report each pre-existing violation in your project as fixed and a new violation in your Ruff upgrade PR.
-
-## 0.0.283 / 0.284
-
-### The target Python version now defaults to 3.8 instead of 3.10 ([#6397](https://github.com/astral-sh/ruff/pull/6397))
-
-Previously, when a target Python version was not specified, Ruff would use a default of Python 3.10. However, it is safer to default to an _older_ Python version to avoid assuming the availability of new features. We now default to the oldest supported Python version which is currently Python 3.8.
-
-(We still support Python 3.7 but since [it has reached EOL](https://devguide.python.org/versions/#unsupported-versions) we've decided not to make it the default here.)

-### `.ipynb_checkpoints`, `.pyenv`, `.pytest_cache`, and `.vscode` are now excluded by default ([#5513](https://github.com/astral-sh/ruff/pull/5513))
-
-Ruff maintains a list of default exclusions, which now consists of the following patterns:
-
-- `.bzr`
-- `.direnv`
-- `.eggs`
-- `.git`
-- `.git-rewrite`
-- `.hg`
-- `.ipynb_checkpoints`

-Black.
-
-## 0.0.276
-
-### The `keep-runtime-typing` setting has been reinstated ([#5470](https://github.com/astral-sh/ruff/pull/5470))
-
-The `keep-runtime-typing` setting has been reinstated with revised semantics. This setting was
-removed in [#4427](https://github.com/astral-sh/ruff/pull/4427), as it was equivalent to ignoring
-the `UP006` and `UP007` rules via Ruff's standard `ignore` mechanism.
-
-Taking `UP006` (rewrite `List[int]` to `list[int]`) as an example, the setting now behaves as
-follows:
-
-- On Python 3.7 and Python 3.8, setting `keep-runtime-typing = true` will cause Ruff to ignore
-    `UP006` violations, even if `from __future__ import annotations` is present in the file.
-    While such annotations are valid in Python 3.7 and Python 3.8 when combined with
-    `from __future__ import annotations`, they aren't supported by libraries like Pydantic and
-    FastAPI, which rely on runtime type checking.
-- On Python 3.9 and above, the setting has no effect, as `list[int]` is a valid type annotation,
-    and libraries like Pydantic and FastAPI support it without issue.
-
-In short: `keep-runtime-typing` can be used to ensure that Ruff doesn't introduce type annotations
-that are not supported at runtime by the current Python version, which are unsupported by libraries
-like Pydantic and FastAPI.
-
-Note that this is not a breaking change, but is included here to complement the previous removal
-of `keep-runtime-typing`.
-
-## 0.0.268
-
-### The `keep-runtime-typing` setting has been removed ([#4427](https://github.com/astral-sh/ruff/pull/4427))
-
-Enabling the `keep-runtime-typing` option, located under the `pyupgrade` section, is equivalent
-to ignoring the `UP006` and `UP007` rules via Ruff's standard `ignore` mechanism. As there's no
-need for a dedicated setting to disable these rules, the `keep-runtime-typing` option has been
-removed.
-
-## 0.0.267
-
-### `update-check` is no longer a valid configuration option ([#4313](https://github.com/astral-sh/ruff/pull/4313))
-
-The `update-check` functionality was deprecated in [#2530](https://github.com/astral-sh/ruff/pull/2530),
-in that the behavior itself was removed, and Ruff was changed to warn when that option was enabled.
-
-Now, Ruff will throw an error when `update-check` is provided via a configuration file (e.g.,
-`update-check = false`) or through the command-line, since it has no effect. Users should remove
-this option from their configuration.

-### `--fix-only` now exits with a zero exit code, unless `--exit-non-zero-on-fix` is specified ([#4146](https://github.com/astral-sh/ruff/pull/4146))
-
-Previously, `--fix-only` would exit with a non-zero exit code if any fixes were applied. This
-behavior was inconsistent with `--fix`, and further, meant that `--exit-non-zero-on-fix` was
-effectively ignored when `--fix-only` was specified.
-
-Now, `--fix-only` will exit with a zero exit code, unless `--exit-non-zero-on-fix` is specified,
-in which case it will exit with a non-zero exit code if any fixes were applied.
-
-## 0.0.260
-
-### Fixes are now represented as a list of edits ([#3709](https://github.com/astral-sh/ruff/pull/3709))
-
-Previously, Ruff represented each fix as a single edit, which prohibited Ruff from automatically
-fixing violations that required multiple edits across a file. As such, Ruff now represents each
-fix as a list of edits.
-
-This primarily affects the JSON API. Ruff's JSON representation used to represent the `fix` field as
-a single edit, like so:
-
-```json
-{
-    "message": "Remove unused import: `sys`",
-    "content": "",
-    "location": {"row": 1, "column": 0},

-

+`flake8-to-ruff` will attempt to infer any activated plugins based on the settings provided in your
+configuration file.
+
+For example, if your `.flake8` file includes a `docstring-convention` property, `flake8-to-ruff`
+will enable the appropriate [`flake8-docstrings`](https://pypi.org/project/flake8-docstrings/)
+checks.
+
+Alternatively, you can manually specify plugins on the command-line:
+
+```shell
+flake8-to-ruff path/to/.flake8 --plugin flake8-builtins --plugin flake8-quotes
+```
+
+## Limitations
+
+1. Ruff only supports a subset of the Flake configuration options. `flake8-to-ruff` will warn on and
+   ignore unsupported options in the `.flake8` file (or equivalent). (Similarly, Ruff has a few
+   configuration options that don't exist in Flake8.)
+1. Ruff will omit any rule codes that are unimplemented or unsupported by Ruff, including rule
+   codes from unsupported plugins. (See the [Ruff README](https://github.com/charliermarsh/ruff#user-content-how-does-ruff-compare-to-flake8)
+   for the complete list of supported plugins.)

-# Tracing
-
-Traces are a useful tool to narrow down the location of a bug or, at least, to understand why the compiler is doing a particular thing.
-Note, tracing messages with severity `debug` or greater are user-facing. They should be phrased accordingly.
-Tracing spans are only shown when using `-vvv`.
-
-## Verbosity levels
-
-The CLI supports different verbosity levels.
-
-- default: Only show errors and warnings.
-- `-v` activates `info!`: Show generally useful information such as paths of configuration files, detected platform, etc., but it's not a lot of messages, it's something you'll activate in CI by default. cargo build e.g. shows you which packages are fresh.
-- `-vv` activates `debug!` and timestamps: This should be enough information to get to the bottom of bug reports. When you're processing many packages or files, you'll get pages and pages of output, but each line is link to a specific action or state change.
-- `-vvv` activates `trace!` (only in debug builds) and shows tracing-spans: At this level, you're logging everything. Most of this is wasted, it's really slow, we dump e.g. the entire resolution graph. Only useful to developers, and you almost certainly want to use `RED_KNOT_LOG` to filter it down to the area your investigating.
-
-## Better logging with `RED_KNOT_LOG` and `RAYON_NUM_THREADS`
-
-By default, the CLI shows messages from the `ruff` and `red_knot` crates. Tracing messages from other crates are not shown.
-The `RED_KNOT_LOG` environment variable allows you to customize which messages are shown by specifying one
-or more [filter directives](https://docs.rs/tracing-subscriber/latest/tracing_subscriber/filter/struct.EnvFilter.html#directives).
-
-The `RAYON_NUM_THREADS` environment variable, meanwhile, can be used to control the level of concurrency red-knot uses.
-By default, red-knot will attempt to parallelize its work so that multiple files are checked simultaneously,
-but this can result in a confused logging output where messages from different threads are intertwined.
-To switch off concurrency entirely and have more readable logs, use `RAYON_NUM_THREADS=1`.
-
-### Examples
-
-#### Show all debug messages
-
-Shows debug messages from all crates.
-
-```bash
-RED_KNOT_LOG=debug
-```
-
-#### Show salsa query execution messages
-
-Show the salsa `execute: my_query` messages in addition to all red knot messages.
-
-```bash
-RED_KNOT_LOG=ruff=trace,red_knot=trace,salsa=info
-```
-
-#### Show typing traces
-
-Only show traces for the `red_knot_python_semantic::types` module.
-
-```bash
-RED_KNOT_LOG="red_knot_python_semantic::types"
-```
-
-Note: Ensure that you use `-vvv` to see tracing spans.
-
-#### Show messages for a single file
-
-Shows all messages that are inside of a span for a specific file.
-
-```bash
-RED_KNOT_LOG=red_knot[{file=/home/micha/astral/test/x.py}]=trace
-```
-
-**Note**: Tracing still shows all spans because tracing can't know at the time of entering the span
-whether one if its children has the file `x.py`.
-
-**Note**: Salsa currently logs the entire memoized values. In our case, the source text and parsed AST.
-This very quickly leads to extremely long outputs.
-
-## Tracing and Salsa
-
-Be mindful about using `tracing` in Salsa queries, especially when using `warn` or `error` because it isn't guaranteed
-that the query will execute after restoring from a persistent cache. In which case the user won't see the message.
-
-For example, don't use `tracing` to show the user a message when generating a lint violation failed
-because the message would only be shown when linting the file the first time, but not on subsequent analysis
-runs or when restoring from a persistent cache. This can be confusing for users because they
-don't understand why a specific lint violation isn't raised. Instead, change your
-query to return the failure as part of the query's result or use a Salsa accumulator.
-
-## Tracing in tests
-
-You can use `ruff_db::testing::setup_logging` or `ruff_db::testing::setup_logging_with_filter` to set up logging in tests.
-
-```rust
-use ruff_db::testing::setup_logging;
-
-#[test]
-fn test() {
-  let _logging = setup_logging();
-
-  tracing::info!("This message will be printed to stderr");
-}
-```
-
-Note: Most test runners capture stderr and only show its output when a test fails.
-
-Note also that `setup_logging` only sets up logging for the current thread because [`set_global_default`](https://docs.rs/tracing/latest/tracing/subscriber/fn.set_global_default.html) can only be
-called **once**.
-
-## Release builds
-
-`trace!` events are removed in release builds.
-
-## Profiling
-
-Red Knot generates a folded stack trace to the current directory named `tracing.folded` when setting the environment variable `RED_KNOT_LOG_PROFILE` to `1` or `true`.
-
-```bash
-RED_KNOT_LOG_PROFILE=1 red_knot -- --current-directory=../test -vvv
-```
-
-You can convert the textual representation into a visual one using `inferno`.
-
-```shell
-cargo install inferno
-```
-
-```shell
-# flamegraph
-cat tracing.folded | inferno-flamegraph > tracing-flamegraph.svg
-
-# flamechart
-cat tracing.folded | inferno-flamegraph --flamechart > tracing-flamechart.svg
-```

-# `Annotated`
-

-## Usages
-
-`Annotated[T, ...]` is equivalent to `T`: All metadata arguments are simply ignored.
-
-```py
-from typing_extensions import Annotated
-
-def _(x: Annotated[int, "foo"]):
-    reveal_type(x)  # revealed: int
-
-def _(x: Annotated[int, lambda: 0 + 1 * 2 // 3, _(4)]):

-## Annotation
-
-`typing.Any` is a way to name the Any type.

-from typing import Any

-x = "foo"
-
-def f():

-# `LiteralString`
-
-`LiteralString` represents a string that is either defined directly within the source code or is
-made up of such components.
-
-Parts of the testcases defined here were adapted from [the specification's examples][1].
-
-## Usages
-
-### Valid places
-
-It can be used anywhere a type is accepted:
-
-```py
-from typing_extensions import LiteralString
-
-x: LiteralString
-
-def f():
-    reveal_type(x)  # revealed: LiteralString
-```
-
-### Within `Literal`
-
-`LiteralString` cannot be used within `Literal`:
-
-```py
-from typing_extensions import Literal, LiteralString
-
-bad_union: Literal["hello", LiteralString]  # error: [invalid-type-form]
-bad_nesting: Literal[LiteralString]  # error: [invalid-type-form]
-```
-
-### Parameterized
-
-`LiteralString` cannot be parameterized.
-
-```py
-from typing_extensions import LiteralString
-
-a: LiteralString[str]  # error: [invalid-type-form]
-b: LiteralString["foo"]  # error: [invalid-type-form]
-```
-
-### As a base class
-
-Subclassing `LiteralString` leads to a runtime error.
-
-```py
-from typing_extensions import LiteralString
-
-class C(LiteralString): ...  # error: [invalid-base]
-```
-
-## Inference
-
-### Common operations
-
-```py
-from typing_extensions import LiteralString
-
-foo: LiteralString = "foo"
-reveal_type(foo)  # revealed: Literal["foo"]
-
-bar: LiteralString = "bar"
-reveal_type(foo + bar)  # revealed: Literal["foobar"]
-
-baz: LiteralString = "baz"
-baz += foo
-reveal_type(baz)  # revealed: Literal["bazfoo"]
-
-qux = (foo, bar)
-reveal_type(qux)  # revealed: tuple[Literal["foo"], Literal["bar"]]
-
-# TODO: Infer "LiteralString"
-reveal_type(foo.join(qux))  # revealed: @Todo(Attribute access on `StringLiteral` types)
-
-template: LiteralString = "{}, {}"
-reveal_type(template)  # revealed: Literal["{}, {}"]
-# TODO: Infer `LiteralString`
-reveal_type(template.format(foo, bar))  # revealed: @Todo(Attribute access on `StringLiteral` types)
-```
-
-### Assignability
-
-`Literal[""]` is assignable to `LiteralString`, and `LiteralString` is assignable to `str`, but not
-vice versa.
-
-```py
-from typing_extensions import Literal, LiteralString
-
-def _(flag: bool):
-    foo_1: Literal["foo"] = "foo"
-    bar_1: LiteralString = foo_1  # fine
-
-    foo_2 = "foo" if flag else "bar"
-    reveal_type(foo_2)  # revealed: Literal["foo", "bar"]
-    bar_2: LiteralString = foo_2  # fine
-
-    foo_3: LiteralString = "foo" * 1_000_000_000
-    bar_3: str = foo_2  # fine
-
-    baz_1: str = str()
-    qux_1: LiteralString = baz_1  # error: [invalid-assignment]
-
-    baz_2: LiteralString = "baz" * 1_000_000_000
-    qux_2: Literal["qux"] = baz_2  # error: [invalid-assignment]
-
-    baz_3 = "foo" if flag else 1
-    reveal_type(baz_3)  # revealed: Literal["foo"] | Literal[1]
-    qux_3: LiteralString = baz_3  # error: [invalid-assignment]
-```

-
-## Unions with possibly unbound paths
-
-### Definite boundness within a class
-
-In this example, the `x` attribute is not defined in the `C2` element of the union:
-
-```py
-def _(flag1: bool, flag2: bool):
-    class C1:
-        x = 1
-
-    class C2: ...

-    C = C1 if flag1 else C2 if flag2 else C3
-
-    # error: [possibly-unbound-attribute] "Attribute `x` on type `Literal[C1, C2, C3]` is possibly unbound"
-    reveal_type(C.x)  # revealed: Literal[1, 3]
-```
-
-### Possibly-unbound within a class
-
-We raise the same diagnostic if the attribute is possibly-unbound in at least one element of the
-union:
-
-```py
-def _(flag: bool, flag1: bool, flag2: bool):
-    class C1:
-        x = 1
-
-    class C2:
-        if flag:
-            x = 2
-
-    class C3:
-        x = 3
-
-    C = C1 if flag1 else C2 if flag2 else C3
-
-    # error: [possibly-unbound-attribute] "Attribute `x` on type `Literal[C1, C2, C3]` is possibly unbound"
-    reveal_type(C.x)  # revealed: Literal[1, 2, 3]
-```
-
-## Unions with all paths unbound
-
-If the symbol is unbound in all elements of the union, we detect that:
-
-```py
-def _(flag: bool):
-    class C1: ...
-    class C2: ...
-    C = C1 if flag else C2
-
-    # error: [unresolved-attribute] "Type `Literal[C1, C2]` has no attribute `x`"

-Most attribute accesses on bool-literal types are delegated to `builtins.bool`, since all literal
-bols are instances of that class:

-## Operations
-
-We support inference for all Python's binary operators: `+`, `-`, `*`, `@`, `/`, `//`, `%`, `**`,
-`<<`, `>>`, `&`, `^`, and `|`.
-
-```py

-
-## Reflected
-
-We also support inference for reflected operations:
-
-```py
-class A:

-        return self
-
-    def __rsub__(self, other) -> A:

-reveal_type(B() & A())  # revealed: A
-reveal_type(B() ^ A())  # revealed: A
-reveal_type(B() | A())  # revealed: A
-```
-
-## Returning a different type
-
-The magic methods aren't required to return the type of `self`:
-
-```py
-class A:
-    def __add__(self, other) -> int:
-        return 1
-
-    def __rsub__(self, other) -> int:
-        return 1
-
-class B: ...
-
-reveal_type(A() + B())  # revealed: int
-reveal_type(B() - A())  # revealed: int
-```
-
-## Non-reflected precedence in general
-
-In general, if the left-hand side defines `__add__` and the right-hand side defines `__radd__` and
-the right-hand side is not a subtype of the left-hand side, `lhs.__add__` will take precedence:
-
-```py
-class A:
-    def __add__(self, other: B) -> int:
-        return 42
-
-class B:
-    def __radd__(self, other: A) -> str:
-        return "foo"
-
-reveal_type(A() + B())  # revealed:  int
-
-# Edge case: C is a subtype of C, *but* if the two sides are of *equal* types,
-# the lhs *still* takes precedence
-class C:
-    def __add__(self, other: C) -> int:
-        return 42
-
-    def __radd__(self, other: C) -> str:
-        return "foo"
-
-reveal_type(C() + C())  # revealed: int
-```
-
-## Reflected precedence for subtypes (in some cases)
-
-If the right-hand operand is a subtype of the left-hand operand and has a different implementation
-of the reflected method, the reflected method on the right-hand operand takes precedence.
-
-```py
-class A:
-    def __add__(self, other) -> str:
-        return "foo"
-
-    def __radd__(self, other) -> str:
-        return "foo"
-
-class MyString(str): ...
-
-class B(A):
-    def __radd__(self, other) -> MyString:
-        return MyString()
-
-reveal_type(A() + B())  # revealed: MyString
-
-# N.B. Still a subtype of `A`, even though `A` does not appear directly in the class's `__bases__`
-class C(B): ...
-
-reveal_type(A() + C())  # revealed: MyString
-```
-
-## Reflected precedence 2
-
-If the right-hand operand is a subtype of the left-hand operand, but does not override the reflected
-method, the left-hand operand's non-reflected method still takes precedence:
-
-```py
-class A:
-    def __add__(self, other) -> str:
-        return "foo"
-
-    def __radd__(self, other) -> int:
-        return 42
-
-class B(A): ...
-
-reveal_type(A() + B())  # revealed: str
-```
-
-## Only reflected supported
-
-For example, at runtime, `(1).__add__(1.2)` is `NotImplemented`, but `(1.2).__radd__(1) == 2.2`,
-meaning that `1 + 1.2` succeeds at runtime (producing `2.2`). The runtime tries the second one only
-if the first one returns `NotImplemented` to signal failure.
-
-Typeshed and other stubs annotate dunder-method calls that would return `NotImplemented` as being
-"illegal" calls. `int.__add__` is annotated as only "accepting" `int`s, even though it
-strictly-speaking "accepts" any other object without raising an exception -- it will simply return
-`NotImplemented`, allowing the runtime to try the `__radd__` method of the right-hand operand as
-well.
-
-```py
-class A:
-    def __sub__(self, other: A) -> A:
-        return A()
-
-class B:
-    def __rsub__(self, other: A) -> B:
-        return B()
-
-# TODO: this should be `B` (the return annotation of `B.__rsub__`),
-# because `A.__sub__` is annotated as only accepting `A`,
-# but `B.__rsub__` will accept `A`.
-reveal_type(A() - B())  # revealed: A
-```
-
-## Callable instances as dunders
-
-Believe it or not, this is supported at runtime:
-
-```py
-class A:
-    def __call__(self, other) -> int:
-        return 42
-
-class B:
-    __add__ = A()
-
-reveal_type(B() + B())  # revealed: int
-```
-

-reveal_type(4.2 + 42)  # revealed: float
-reveal_type(3j + 3)  # revealed: complex

-    reveal_type(x + y)  # revealed: int
-    reveal_type(4.2 + x)  # revealed: float
-
-    # TODO should be float, need to check arg type and fall back to `rhs.__radd__`
-    reveal_type(y + 4.12)  # revealed: int
-```
-
-## With literal types
-
-When we have a literal type for one operand, we're able to fall back to the instance handling for
-its instance super-type.
-
-```py
-class A:
-    def __add__(self, other) -> A:
-        return self
-
-    def __radd__(self, other) -> A:
-        return self
-
-reveal_type(A() + 1)  # revealed: A
-# TODO should be `A` since `int.__add__` doesn't support `A` instances
-reveal_type(1 + A())  # revealed: int
-
-reveal_type(A() + "foo")  # revealed: A
-# TODO should be `A` since `str.__add__` doesn't support `A` instances
-# TODO overloads
-reveal_type("foo" + A())  # revealed: @Todo(return type)
-
-reveal_type(A() + b"foo")  # revealed: A
-# TODO should be `A` since `bytes.__add__` doesn't support `A` instances
-reveal_type(b"foo" + A())  # revealed: bytes
-
-reveal_type(A() + ())  # revealed: A
-# TODO this should be `A`, since `tuple.__add__` doesn't support `A` instances
-reveal_type(() + A())  # revealed: @Todo(return type)
-
-literal_string_instance = "foo" * 1_000_000_000
-# the test is not testing what it's meant to be testing if this isn't a `LiteralString`:
-reveal_type(literal_string_instance)  # revealed: LiteralString
-
-reveal_type(A() + literal_string_instance)  # revealed: A
-# TODO should be `A` since `str.__add__` doesn't support `A` instances
-# TODO overloads
-reveal_type(literal_string_instance + A())  # revealed: @Todo(return type)
-```
-
-## Operations involving instances of classes inheriting from `Any`
-
-`Any` and `Unknown` represent a set of possible runtime objects, wherein the bounds of the set are
-unknown. Whether the left-hand operand's dunder or the right-hand operand's reflected dunder depends
-on whether the right-hand operand is an instance of a class that is a subclass of the left-hand
-operand's class and overrides the reflected dunder. In the following example, because of the
-unknowable nature of `Any`/`Unknown`, we must consider both possibilities: `Any`/`Unknown` might
-resolve to an unknown third class that inherits from `X` and overrides `__radd__`; but it also might
-not. Thus, the correct answer here for the `reveal_type` is `int | Unknown`.
-
-```py
-from does_not_exist import Foo  # error: [unresolved-import]
-
-reveal_type(Foo)  # revealed: Unknown
-
-class X:
-    def __add__(self, other: object) -> int:
-        return 42
-
-class Y(Foo): ...
-
-# TODO: Should be `int | Unknown`; see above discussion.
-reveal_type(X() + Y())  # revealed: int
-```
-
-## Unsupported
-
-### Dunder as instance attribute
-
-The magic method must exist on the class, not just on the instance:
-
-```py
-def add_impl(self, other) -> int:
-    return 1
-
-class A:
-    def __init__(self):
-        self.__add__ = add_impl
-
-# error: [unsupported-operator] "Operator `+` is unsupported between objects of type `A` and `A`"
-# revealed: Unknown
-reveal_type(A() + A())
-```
-
-### Missing dunder
-
-```py
-class A: ...
-
-# error: [unsupported-operator]
-# revealed: Unknown
-reveal_type(A() + A())
-```
-
-### Wrong position
-
-A left-hand dunder method doesn't apply for the right-hand operand, or vice versa:
-
-```py
-class A:
-    def __add__(self, other) -> int: ...
-
-class B:
-    def __radd__(self, other) -> int: ...
-
-class C: ...
-
-# error: [unsupported-operator]
-# revealed: Unknown
-reveal_type(C() + A())
-
-# error: [unsupported-operator]
-# revealed: Unknown
-reveal_type(B() + C())
-```
-
-### Reflected dunder is not tried between two objects of the same type
-
-For the specific case where the left-hand operand is the exact same type as the right-hand operand,
-the reflected dunder of the right-hand operand is not tried; the runtime short-circuits after trying
-the unreflected dunder of the left-hand operand. For context, see
-[this mailing list discussion](https://mail.python.org/archives/list/python-dev@python.org/thread/7NZUCODEAPQFMRFXYRMGJXDSIS3WJYIV/).
-
-```py
-class Foo:
-    def __radd__(self, other: Foo) -> Foo:
-        return self
-
-# error: [unsupported-operator]
-# revealed: Unknown
-reveal_type(Foo() + Foo())
-```
-
-### Wrong type

-## Division by Zero
-
-This error is really outside the current Python type system, because e.g. `int.__truediv__` and
-friends are not annotated to indicate that it's an error, and we don't even have a facility to
-permit such an annotation. So arguably divide-by-zero should be a lint error rather than a type
-checker error. But we choose to go ahead and error in the cases that are very likely to be an error:
-dividing something typed as `int` or `float` by something known to be `Literal[0]`.
-
-This isn't _definitely_ an error, because the object typed as `int` or `float` could be an instance
-of a custom subclass which overrides division behavior to handle zero without error. But if this
-unusual case occurs, the error can be avoided by explicitly typing the dividend as that safe custom
-subclass; we only emit the error if the LHS type is exactly `int` or `float`, not if its a subclass.
-
-```py
-a = 1 / 0  # error: "Cannot divide object of type `Literal[1]` by zero"
-reveal_type(a)  # revealed: float
-
-b = 2 // 0  # error: "Cannot floor divide object of type `Literal[2]` by zero"
