That's too bad...do you have a link to prior discussion on this and what the reasoning was for rejection? There doesn't seem to be any particular downside and things would be more consistent with slice syntax allowed anywhere.

It would be helpful in other cases as well other than the one linked to, since there's good reason to be able to succinctly create and reuse the same indexer object multiple times without having to convert everything into slice() calls.
