[docs] [issue16195] Difficult or impossible to figure out how garbage collector and weak references should interact for user-defined extension types

[Antoine Pitrou]

Antoine Pitrou added the comment:

I think Cython is wrong here. The only thing to do is to call PyObject_ClearWeakRefs() in the deallocator. Everything else is handled by the interpreter.

Agreed improving the documentation would be good.
