[Python-Dev] Re: Discrepancy between what aiter() and `async for` requires on purpose?

I think the C implementation of PyAiter_Check was a translation of the Python code `isinstance(..., collections.abc.AsyncIterator)`, but I agree that it would be more consistent to just check for __anext__. There were comments at the time here: https://github.com/python/cpython/pull/8895#discussion_r532833905
