What if the "self" passed to __del__ was instead a weakref.proxy, or a
similar wrapper object which does not give you access to the object itself
but lets you access its attributes? The object could have been already
collected for what I care, what I really need is to be able to say
"self.foo" to access what used to be a "foo" member of self. You can create
a totally different object of any type but with the same __dict__. Ok, it's
not that easy (properties, etc.), but you get the idea.

Am I missing something?
