Another way to do that:

use 5.010;
my $t = $s1 ^ $s2;
$t =~ /^\0*/ && say $+[0]

JavaFan and jwkrahn, *C o o l !* That's the code I was hoping for... Need to benchmark now! UPDATE: My apologies to JavaFan, I didn't realize his post was first. Both solutions Benchmarked are better than mine (376%). Thank you "Well done is better than well said." - Benjamin Franklin	[reply]
