## Summary
Use the type annotation of function parameters as bidirectional type
context when inferring the argument expression. For example, the
following example now type-checks:
```py
class TD(TypedDict):
x: int
def f(_: TD): ...
f({ "x": 1 })
```

Ruff Benchmarks
The ruff_benchmark crate benchmarks the linter and the formatter on individual files:
# Run once on the "baseline".
cargo bench -p ruff_benchmark -- --save-baseline=main
# Compare against the "baseline".
cargo bench -p ruff_benchmark -- --baseline=main
# Run the lexer benchmarks.
cargo bench -p ruff_benchmark lexer -- --baseline=main
See CONTRIBUTING.md on how to use these benchmarks.
