Sure. The 3.0 range() isn't exactly the same as the 2.6 xrange(), so
it would have to be a proper backport (sorry, I don't recall the exact
difference, but I remember it's been redone, perhaps to support long

It seems pretty minor though. The advantage of using xrange() is that
you remain backwards compatible all the way to 2.0 and probably even
