Self doesn't support an async iterator protocol

[erwinkinn]

Hello.
I've got a problem with Self type when using it as it's done in types-aiofiles
I've made a merge request, trying to fix it in there, but to be honest it looks like this problem relates to the async iterator protocol's support for the tying_extensions.Self type.
Whether it's possible to make such a thing?

This seems like a mypy bug to me. typing-extensions doesn't really affect how type checkers interpret Self: the runtime Self object does very little. Please report your issue to mypy instead (ideally with a full, standalone sample that reproduces the bug).

Hi, I think you've stumbled across a mypy bug, there is nothing in PEP 673 that stipulates that Self cannot be used inside of the async iterator protocol furthermore, running your code in your issue pyright there are no complaints.

Make sure you're using mypy 1.0 or newer
