I personally think that "bare maps...maps that don't use the output of the map" are not a good idea although other Monks would disagree.
Uhm, Perl is context driven. Whether operations "output" 0, 1 or many things isn't up to them. It's up to the context. void context means an operator doesn't return any values.
