in thread How to avoid warnings in HTML::Template::Pro?

I am sorry for the late follow up on this. I got stuck with some other things. However let me tell you that the problem got solved for me. It was a bug in my code. When I fixed it this problem vanished! I am very much grateful for the help provided by the anonymous monk and Marshall.

I appreciate Marshall's detailed description of defined checks. Talking about them I think it's worthy to mention the handy new defined-or operator // which got introduced in perl 5.10. It can be used for some of the cases in Marshall's examples also.

    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.
