Yes, it's range(len(s)).

In the same vein as zip(), i think it's much easier to just toss in
a couple of built-ins than try to settle on a new syntax.  (I already
uploaded a patch to add indices() and irange() to the built-ins,
immediately after i posted my first message on this thread.)

Surely a PEP isn't required for a couple of built-in functions that
are simple and well understood?  You can just call thumbs-up or
thumbs-down and be done with it.
