This is a great start, Nick.  Having a solid sys.implementation would
(for one) help with the import machinery, as your list suggests.  I'm

sys.implementation would be very helpful.

p.s. is python-ideas the right place for this discussion?  Also,
ultimately this topic should go into a PEP, right?
