Seems good to me. Lots of flexibility. I may begin to write output ranges :-)

So in the very first case, e may well be a range, but the way it's used internally is up to the output range designer. Maybe it uses a loop, maybe not. OK.

You call r(e) and r([e])) 'delegates'. Are you just using it as a generic term, or does that mean using any callable (struct with opCall) is not a good idea in this case, for whatever reason?
