I think you, Skip and Moshe are missing a big advantage of having
the __exports__ mechanism.  It should allow some attribute access
inside of modules to become faster (like LOAD_FAST for locals).
I think that optimization could be implemented without too much
difficultly.  I've never channeled Guido before so I could be off
the mark.  If the only advantage is encapsulation then I'm -0.
