Deque.pop() takes no arguments

[KmolYuan]

According to:
https://docs.python.org/3.8/library/collections.html#collections.deque.pop
But still an argument "i" there:

Good spot, PR welcome. One issue is that MutableSequence's pop takes an argument (https://github.com/python/cpython/blob/3.8/Lib/_collections_abc.py#L985), so you might run into issues or need to type ignore incompatible override complaints

I wonder if deque.pop(index) is supposed to raise an exception. You can del deque[index], for example, so why would deque.pop(index) be unsupported, other than by accident?

@Akuli that does sound accidental; feel free to submit an issue to CPython.
