[issue25994] File descriptor leaks in os.scandir()

[Martin Panter]

Martin Panter added the comment:

Contextlib.closing() cannot be used in general, because it doesn’t inherit the iterator protocol from the wrapped generator. So I think you really need a class that implements __exit__(), __iter__(), etc at the same time.
