Yes, it does still resort to setting globals to None. However, the weakref step makes it much more likely that del methods run before that happens. After this change, referencing global variables from del methods is okay.

The first and last sentences seem like a contradiction to me. If I cannot guarantee that globals will be valid when del is executed, then I must not reference globals from del.

I think I'm missing something here. Is there some way the programmer can determine that referencing a global variable in del will be 100% safe? (not just "likely")
