It sounds as if you might want something like Algorithm::Loops::NestedLoops (among many similar on CPAN): 

>perl -wMstrict -le
"my $number = 99;
 my $letter = 'Z';
 my $word   = 'zot';
 ;;
 my @words= qw(foo bar);
 ;;
 for my $number (1 .. 3) {
   for my $letter (qw(A B C)) {
     for my $word (@words) {
       do_something_with($number, $letter, $word);
       }
     }
   }
 ;;
 print qq{post-loop: '$number' '$letter' '$word' \n}
 ;;
 sub do_something_with {
   my (@args) = @_;
   ;;
   print qq{@args};
   }
 ;;
 ;;
 use Algorithm::Loops qw(NestedLoops);
 ;;
 print qq{using NestedLoops:};
 NestedLoops
   [ [ 1 .. 3 ],  [ qw(A B C) ],  \@words, ],
   \&do_something_with
   ;
"
1 A foo
1 A bar
1 B foo
1 B bar
1 C foo
1 C bar
2 A foo
2 A bar
2 B foo
2 B bar
2 C foo
2 C bar
3 A foo
3 A bar
3 B foo
3 B bar
3 C foo
3 C bar
post-loop: '99' 'Z' 'zot'

using NestedLoops:
1 A foo
1 A bar
1 B foo
1 B bar
1 C foo
1 C bar
2 A foo
2 A bar
2 B foo
2 B bar
2 C foo
2 C bar
3 A foo
3 A bar
3 B foo
3 B bar
3 C foo
3 C bar

With this approach it's easy to add arrays to arbitrary depth, albeit with attendant exponential explosion!

Update: Changed example code to show  \@words taking reference to array.
