logilab-astng #72355 E1101 false positive for collections.deque descendants [open]

Pylint 0.24 marks a false positive E1101 when using any of collections.deque methods in a class inheriting from it.

For a brief example:

"""
A collection of better collections.
"""

import collections

class BetterDeque(collections.deque):
    """
    A deque that is clearly better.
    """

    def popright(self):
        """
        Same as *pop()*, but named consistently.
        """
        return self.pop()

Will produce E: 16:BetterDeque.popright: Instance of 'BetterDeque' has no 'pop' member, which is clearly invalid.

I suppose this might be because collections.deque is actually defined in _collections.so...
