- Issues
- (🐞) Confusing error message in `.format` call with union
- Docs: mention --no-silence-site-packages
- `@overload` incorrectly reports error if overload param would go to different params of implementation depending on positional vs keyword calling style
- (🐞) error code that is enabled in the config file can't be disabled on the CLI (with `--disable-error-code`)
- Add "is invariant" warning to Set as well as List for situations where a Collection should be used
- variance okay for literals, but not expressions ([1, 2] okay for list[int | None] but [1] + [2] is error)
- Mypy does not detect automatic init generation for fieldless dataclass inheriting from abstract base
- (🐞) TypeGuard behaves inconsistently on instance methods.
- Unexpected incompatible types in assignment (Failed in recursive type checking, nested protocol with generic type)
- Replace implicit reexport with explicit
