Why would I need to use gc for it? I can get the address for almost any object with `__module__`. This kind of thing is used in Django settings module, (specifying strings instead of objects themselves,) so why is it a bad design choice when I want to do it? Also, the pickle module in the standard library uses an object's address to pickle some kinds of objects (classes, functions). Anyway, I'm frustrated from getting a lot of "You're doing it wrong" answers for this question, and I just want an answer, not explanation on why I shouldn't do it. (My question is, "Is there a mature module for these tasks?") Thanks, Ram.
