Hello, I have come across a situation where I find the current weak references interface for extension types insufficient. Currently you only have a tp_weaklistoffset slot, pointing to a PyObject with weak references. However, in my case[1] I _really_ need to be notified when a weak reference is dereferenced. What happens now is that, when you call a weakref object, a simple Py_INCREF is done on the referenced object. It would be easy to implement a new slot to contain a function that should be called when a weak reference is dereferenced. Or, alternatively, a slot or class attribute that indicates an alternative type that should be used to create weak references: instead of the builtin weakref object, a subtype of it, so you can override tp_call. Does this sounds acceptable? Regards. [1] http://bugzilla.gnome.org/show_bug.cgi?id=320428 -- Gustavo J. A. M.
