No, range() has never returned an iterator. In Python 2, it returned a
list, which is iterable. In Python 3, it returns a range object, which
is iterable. And in Python 2, xrange returns an xrange object, which
is also iterable (but less functional than the Py3 range object). None
of these is an iterator.
