Right. All it's doing is reporting a successful, true, match.

You need to fix where the parentheses are being used:

foreach (@str) {
( $num = $_ ) =~ /\d+/;
print "$_ : $num\n";
}

That should work better, and also avoids the confusing and unnecessary
$str temporary scalar that looks too much like the $str[] array. Also,
it's usefully indented, because Readability Matters.
