Punt it when it's no longer useful (py3k); xrange exists for a
reason- most usage just needs to iterate over a range of numbers
(xrange), not instantiate a list of the range, then iterate over said
range (range). Don't much see the point in making stdlib more
wasteful in runtime for an "informally deprecated" func that lots of
folks in the real world still use.
