Ummmmm.....why do we want this? What's wrong with the current
suggestion of using "_"? __exports__ feels somehow wrong to
me. None of the rest of Python has any access control, and
I really like that. A big -1 from me, for what it's worth.

So has adding curly-braces as control structure, with all due respect.
