New submission from Bar Harel: I have encountered a weird behavior in collections.UserList. Using copy.copy() on an instance results in a new instance of UserList but with the same underlying list. Seems like self.copy() works great but __copy__ was not overridden to allow copy.copy to work too. The patch just assigns __copy__ to self.copy triggering the correct behavior.
