[New-bugs-announce] [issue41409] deque.pop(index) is not supported

[Akuli]

New submission from Akuli <akuviljanen17 at gmail.com>:

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?
