- `ClassVar` cannot contain `Self` type in generic classes
- Defaulted TypeVar cannot be set to Never?
- mypy does not narrow between Generic type[_T] and Callable[[Any], _T]
- Write some tests that enforce that disabled_error_codes and enabled_error_codes do not affect program behavior
- [docs] let extra-checks example compile
- The result of `type(TypeVar)` is not hashable
- Errors on @overload in supertype signatures
- False positive error on `**kwargs` with `Mapping[Literal, Any]` type
