- Issues
- Can't narrow `Sequence[<X>]` to `Tuple[<X>, ...]` using `isinstance(..., tuple)`
- Typing Error for Default Lambda Arg when using Generics
- mypy incorrectly tags function argument TypeVar with return type when called from a caller with the same signature
- unused-courotine should trigger when using a coroutine call as a condition without awaiting it
- `assert_never` fails on match-casing `enum` with only one member
- Disallow type(x) if x has a protocol type
- Invalid JUnit XML being generated due to <type> hint
- Maybe add semantical understanding of `assert not TYPE_CHECKING` (similar to `if not TYPE_CHECKING`)?
- (🐞) `Protocol`s that narrow to modules become `Any`
- Cannot use `match case` to destructure any object using `case object(x=y)`
