Yeah, I remembered it once I was mostly already done (it didn't take a
long time).  If the backport script has many omissions I may revisit
it with 3to2.

That and I figure it will be easier to take advantage of things like
the import engine and PEP 382 if it is a scripted backport of
importlib.  If I remember right from pycon, the packaging folks were
looking at a similar strategy.
