Heh. I expect Guido would say "braindead" instead of "advanced" <wink>.
I was amazed to find that-- outside of the test suite --there are fewer than
two dozen uses of xrange() in the entire distribution. I was even more
amazed to find that almost all of them were added by me! All but one are of
the "for yadda in xrange():" variety. The exception is types.py's necessary
XRangeType = type(xrange(0))
Apart from that, I know of several instances of spead-freak code not in the
distribution (and not mine either) that does
infinity = xrange(sys.maxint) # or even via the default-arg trick
for whatever in whatchamacallit:
for i in infinity:
yadda yadda yadda
I figure that will still work.

He *wants* to -- not always possible, though. For example, Guido has little
use for anything but floating-point numbers, but all the crybaby users keep
whining for more string features <wink>.
