- 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)`
- (🐞) Incorrect analysis of `while` loop subject
- `next(iter(<Tuple[...]>))` should be a `Union` of the `Tuple` element types, rather than their most descended common ancestor
- MyPy doesn't understand types-boto 2.49.18.20240205 correctly and fails previously-working code
