This is an unwanted an unexpected behavior, so this is a bug by definition. If it's not easy to fix, it's a different matter. However here's a proposed solution: * for the __mro__: instead of using a tuple, use a new object that inherits from it. This new object should use weak reference for the first item and should return the real object (if available) only in __getitem__(). * __objclass__ can should become a property based on weak references.
