Just for fun.

When hacking this on my mobile I hoped using a "magic" solution might need less keystrokes. 

use strict;
use warnings;

$\ = "\n";
my @a = map {int rand 10} 0..3;
my @b = map {int rand 10} 0..3;

print "IN: (@a)  (@b)";

print
  eval
  join '+' ,
  glob
  join '\*' ,
  map "{$a[$_],$b[$_]}", 0..3;

__END__
perl mult_tuple.pl
IN: (9 8 8 9)  (3 1 7 3)
