Probably because nobody thought about it, but if it had been proposed to
change xrange into an iterator, I'm pretty confident that the suggestion
would have been rejected. xrange objects might be lazily generated, but
they're also sequence types: you can get their length, and you can index
them. (However you can't slice them.) Iterators are not sequence types:
they aren't indexable and you can't get their length.
Ah, but what did they change range() into -- I seem to recall
reading the Python 3.x turned the regular range() into something else...
(from Python <3.x returning a full list)
From the What's New docs, in the Views And Iterators Instead Of Lists
section:
range() now behaves like xrange() used to behave, except it works with
values of arbitrary size. The latter no longer exists.
