Is there one certain way to define if callable returns awaitable? I mean it is possible to reimplement some logic in C. For instance callable can has special flag to this purpose. It's because I'm not sure if my patch handles all possible corner cases so maybe there are more subtle ones. So if the checked object was not declared with async def the only way to check this condition is brute force it manually, I guess.

See #81371 (comment)

I don't think the current approach in this PR is the right approach; we shouldn't be checking against an approved list of method names.

But there is no way to add attribute to builtin function without monkey patching. Do we need new type(s) to this? Such as builtin_coroutine_function_or_method
Or at least add special flag to already exists ones

What if PyCFunctionObject structure contains flags that match co_flags field in code object? Or will they carry the same meaning

This isn't the way to fix this, I am closing this, please continue the discussion on the issue.
