[Python-Dev] xrange vs generators

No, but maybe xrange() should be changed to return an iterator.
E.g. something like this:
def xrange(start, stop, step):
while start < stop:
start += stop
but with the appropriate defaults, and reversal of the test if step <
0, and an error if step == 0, and type checks enforcing ints (or long
ints!), and implemented in C. :-)
Although xrange() objects currently support some sequence algebra,
that is mostly bogus and I don't think anyone in their right mind uses
