[issue45121] Regression in 3.9.7 with typing.Protocol

Shantanu added the comment: As I mentioned in the post, bpo-45081 actually makes this issue worse, since we get a RecursionError. I think `TypeError: Protocols cannot be instantiated` is probably okay behaviour (as opposed to RecursionError), more just unfortunate that it seems to be an una

Shantanu added the comment: Sorry if my message was confusing. Hopefully the following makes things clear: 3.9.6: snippet runs without error 3.9.7, with bpo-44806: (a probably reasonable) TypeError, but a breaking change main, with bpo-45081: RecursionError -- _

[issue45117] `dict` not subscriptable despite using `__future__` typing annotations

Dennis Sweeney added the comment: Hi Stefan, `from __future__ import annotations` only affects annotations -- just the things after the colon. It makes it so that annotations are never evaluated, so things like this work: >>> from __future__ import annotations >>> x: nonsense()()()(

New submission from Yury Selivanov : Per discussion on python-dev (also see the linked email), PyAiter_Check should only check for `__anext__` existence (and not for `__aiter__`) to be consistent with `Py_IterCheck`. While there, I'd like to rename PyAiter_Check to PyAIter_Check and PyObject
