But then you would need yet another parameter to an enhanced range or
the yet to come indici to indicate you want to iterate in reverse, like:

    for i in range("spam", reverse=1): pass
    for in in indici("spam", reverse=1): pass

The nicety of the enhanced iterating-integers proposal is that it gives
a very easy spelling of two of the more frequent usages of iterating
over the (range of the:) length of something once you accept that
integers can count (up/down) and that `count' is spelled `iter' in
Python.  Still haven't made up my mind on that last one:)
