In this case: ```python3 class A: async def close(self): pass with closing(A()): pass ``` Python will raise `RuntimeWarning: coroutine 'A.close' was never awaited`. In another case: ```python3 class B: def close(self): pass async with closing(B()): pass ``` Python will raise `TypeError: object NoneType can't be used in 'await' expression` (because it will try to await result of close method). ----- I was surprised that `contextlib` has no async analogue of this `closing` class, because async scripts often use any kind of closings. Do you think it's better to extract to `asyncclosing` class? ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue41197> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
