An iterator like xrange() is an excellent choice. But, since
the iterator contains that information, why require that that
value be "exported" by the iterator and bound to an externally
visible name? In the case in question, the only thing you need
from the iterator is the StopIteration exception. To me,
exposing the internal state of the iterator and requiring that
the user bind a name to it each time through the loop feels
we're like driving a nail with a screwdriver.
