- Issues
- variable annotated as `tuple[SomeProtocol, ...]` loses protocol information on assignment
- abstract class shouldn't be considered Callable
- Annotation parsing incorrect when class scope defines same name as import
- (🐞) false negative with `dataclass` "non-default argument follows default argument"
- Mypy incorrectly infers that parameters are positional-only for `__eq__` methods autogenerated with `@dataclass`
- Change final classes without __bool__ method to always be True
- Only allow splatting iterables if function takes at least one positional arg
- no error when value of type `type` (aka `type[Any]`) passed to function with generic with constraint, generic inferred as the first constraint
- Add support for PEP-610 editable packages (#12313)
- Type-checking generic of enum.Meta with a custom metaclass fails with code that runs, and passes with code that doesn't run.
