I forget what indices() was -- is it the moreal equivalent of keys()?

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

If irange(s) is zip(range(len(s)), s), I see how that's a bit unwieldy. In the past there were syntax proposals, e.g. ``for i indexing s''. Maybe you and Just can draft a PEP?

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.
