Thanks for your thanks and notes on Perl 5.10! Have a happy holiday too!

I will keep in mind Perl 5.10 I still work a lot with Perl 5.8 and thank goodness to a much lesser extent with 5.6!

$a // $b means:   defined $a ? $a : $b
$c //= $d; means: $c = $d unless defined $c;
This is a bit different than $c ||= $d in <Perl 5.10.
