## Summary Properly preserve type qualifiers when accessing attributes on unions and intersections. This is a prerequisite for https://github.com/astral-sh/ruff/pull/19579. Also fix a completely wrong implementation of `map_with_boundness_and_qualifiers`. It now closely follows `map_with_boundness` (just above). ## Test Plan I thought about it, but didn't find any easy way to test this. This only affected `Type::member`. Things like validation of attribute writes (where type qualifiers like `ClassVar` and `Final` are important) were already handling things correctly.
Markdown files within the mdtest/ subdirectory are tests of type inference and type checking;
executed by the tests/mdtest.rs integration test.
See crates/ty_test/README.md for documentation of this test format.
