As such, I think that it is less Pythonic than we might want. Myself, I've been programming in Python for a decade, and I still haven't dug very deeply into what exactly __name__ means or does.

And if that's a good idea, I would invite a discussion of how, exactly, it should be implemented. I'm nowhere near proposing a PEP, but that may come later.
