I'd probably put the our ($a,$b) outside of that block, but this is what I had in mind. I was just interested in more options. - Thanks

out ($a, $b); reduce { $a * $b } 1 .. 6;

    I was just interested in more options.

    This is kind of old-school and amounts to the same thing as sticking an  our ($a, $b); statement somewhere, but it's another option:

    >perl -wMstrict -le "use List::Util qw/reduce/; use vars qw($a $b); ;; print reduce { $a * $b } 1..6; " 720
