The pop method of collections.deque can't be used like deque.pop(index), even though `del deque[index]` or deque.pop() without an argument works. This breaks the Liskov substitution principle because collections.abc.MutableMapping supports the .pop(index) usage. Is this intentional? related typeshed issue: https://github.com/python/typeshed/issues/4364
