It should be possible that an awaitable object does not have a
__code__, so technically checking for the__code__attribute in_is_async_objis incorrect. This faulty code check is also why things like:mock.MagicMock(spec=lambda x: x)evaluate to True, even though they are not asynchronous.https://bugs.python.org/issue37251
