I find it's good practice to "capture" your capture variables immediately after a match even when you know for sure you will never be doing any further regex matching within that scope: 

if ($macs[1] =~ /(\S{17})\|(\S{17})/) {
    my ($mac1, $mac2) = ($1, $2);
    ...
    $mac1 =~ s/.../etc/g;
    $mac2 =~ s/as/needed/g;
    ...
    do_something_with($mac1, $mac2);
    ...
    }

Just make this same, silly mistake as many times as I have and you'll never do otherwise!

Give a man a fish:  <%-{-{-{-<
