Hello, I have several arrays, kets say: 
@a1 = qw(0 1 2 3  4);
@a2 = qw(0 1 2 3 4 5 6 7 8);
@a3 = qw(0 1);
@a4 = qw(0 1 2 3 4 5);

I would like to generates simply (without for loops) the all permutation strings (5 x 9 x 2 x 6 options) 
$str = $a1[$i] . " " . $a2[$j] . " ". $a3[$k]. " " . $a4[$l]

Any simple solution ? Thanks azaria
