+1 QOTW.

I recently gave up on trying to support (backport to) pre-2.2 in my
projects.  It's been ~3 years since 2.2 released and that seem like a
pretty reasonable support window.  I wound up with HACK and
PORTABILITY comments all over the place and too much boilerplate.  Now
I go with a startup check on sys.hexversion, and exit with similar
wording.
