Loops impose order. Maps do not.

Maps are in principle trivial to parallelise. That would be a nice feature.

Agree, and a map also provides an "at a glance" assurance that I'm getting a transformed array of the same size. For loops take longer to discern what they're doing just because they could be doing almost anything, including early exit.
