No problem.  Let me just set the time machine for 2006 and add it to 
pkgutil instead, so it'll be in Python 2.5+.  How dos the name 
'iter_modules()' sound?  ;-)

Since I'm not doing the actual work for 3.3, I don't really care how 
it gets done.  I just don't want to make the *specification* depend 
on that, which is why I'm saying "imp" for the API rather than 
importlib.  When importlib goes in, after all, imp will be importing 
lots of other things from it anyway.  ;-)

That all being said, if somebody Pronounces that importlib is the 
right place to expose it, that's fine too.

(Presumably pkgutil will need some refactoring as well, since it 
currently simulates some things that're probably alo implemented in importlib.)
