Is such a small performance difference more important to you than
backwards compatibility?

I would choose "for i in xrange()" still, merely because of the
number of people still using Python 2.2 and before, but I'm not
one who cares much about trivial optimizations...

(I realize you might be using 2.3-only features, but I don't think
that automatically means you should abandon readability, by dumping
a well-known idiom with a merely possibly-to-become-idiomatic form.)
