docs: Removes all the entries with the given key and returns the value list associated with this key.
  
          **Warning: This method uses __hash__ and __eq__ methods of binary form of the key, not the actual implementations
          of __hash__ and __eq__ defined in key's class.**
  
          **Warning-2:
          The returned list is NOT backed by the map, so changes to the map are NOT reflected in the list, and
          vice-versa.**
  
          :param key: (object), the key of the entries to remove.
          :return: (Sequence), the collection of removed values associated with the given key.
