Can we make it opt-in, by replacing the module __dict__ when and only if 
needed? Perhaps we could replace it on the fly with a dict subclass that 
defines __missing__? That's virtually the same as __getattr__.

Then modules which haven't replaced their __dict__ would not see any 
slow down at all.

Does any of this make sense, or am I talking nonsense on stilts?
