> 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.
I'm afraid doing so could cause some public C API change. For example, the PyDescr_TYPE, if we implemented all the Descriptor object's d_type(that is the __objclass__ of all types of descriptors) based on weakref, we could have all the callers who call the descriptor functions to check weather the weak-referented class object has gone away. |
