```
from __future__ import annotations
from typing import Generic, TypeVar

T = TypeVar("T")
class Foo(Generic[T]): ...
class Bar(Foo[Buzz]): ... # NameError here
class Buzz: ...
```

This will error, despite the __future__ import, because cpython is trying
to look up Buzz before it's defined, even though we have supposedly
prevented annotations from being processed. I realize that Class[Args] is allowed in that area in general and isn't always type annotation related,
but does this mean that even with PEP 649 that forward references will
still be needed?

Should mention this also affects Protocol[Buzz]

Yes. Both of PEP 563 and PEP 649 solves not all forward reference issues.
