To have a non-hackish patch we need a non-hackish idea. The `.__parent_class__` idea looks hackish to me, but now that I think about it, how is it more hackish than a function's `.__module__` attribute?

I mean, a function's `.__module__` attribute says on which module the function was originally defined, but the function could be accessible on any other module and any other namespace or class. Its `.__module__` would remain constant, because it's the one place where you are guaranteed to be able to find the function, assuming it's defined in the top-level. So the `.__module__` attribute is used in unpickling the function. How is the `.__parent_class__` suggestion more hackish than `.__module__`?
