Other situations like this (was RE: [Python-Dev] Nested scopes resolution -- you can breathe again!)

Excellent, Tim!  Let's PEP this sucker.

The only suggestion I was going to make was to use sys.hexversion
instead of sys.version_info.  Something about tuples-of-tuples kind of
bugged me.

But after composing the response to suggest this, I looked at it
closely, and decided that sys.version_info is right after all.  Both
are equally comparable and sys.version_info is more "human friendly".
