If we're going to use any sort of ellipsis syntax here, I
think it would be highly preferable to use the ellipsis
token we've already got. I can't see any justification for
having two different ellipsis-like tokens in the language,
when there would be no ambiguity in using one for both
purposes.

Am I right in thinking that the main motivation here is
to clean up the "for i in range(len(a))" idiom? If so,
what's wrong with a built-in:

  def indices(a):
    return range(len(a))
