Re^2: Processing pairs of values from even-sized array

Have you tried using each itself.

This doesn't work, because this would require $array being a hash reference.

Interestingly, the 5.12+ each allows iteration over an array (and similarly for keys and values), but each 'key' is a succcessive index of the array, and each 'value' is the element at that index: not quite what you wanted in the OP. `>perl -wMstrict -le "my @ra = qw(a b c d); ;; while (my ($i, $element) = each @ra) { print qq{ra $i is '$element'}; } " ra 0 is 'a' ra 1 is 'b' ra 2 is 'c' ra 3 is 'd'` [download]	[reply] [d/l]

>perl -wMstrict -le
"my @ra = qw(a b c d);
 ;;
 while (my ($i, $element) = each @ra) {
   print qq{ra $i is '$element'};
   }
"
ra 0 is 'a'
ra 1 is 'b'
ra 2 is 'c'
ra 3 is 'd'
