in reply to List::MoreUtils before, after and ... between?

BTW: If the your main concern with your method, is the time taken to perform the reverses, don't even consider it unless your list is huge. Reverse is a particularly efficient operation. 1000 items take a just 2/10s of a millisecond:

@a = 1 .. 1e3;;

$t = time; @a = reverse @a; print time() - $t;;
0.000192165374755859

$t = time; @a = reverse @a; print time() - $t;;
0.000243186950683594

$t = time; @a = reverse @a; print time() - $t;;
0.000186920166015625
