Very much enjoyed your review. I do, however, have some questions.

1. I understand the idea of a symbolic reference, but I'm not sure how you'd go about creating one. I'd like to know that so I can avoid it. Might it be something like this:

$a = "Amel"; $b = \$a; # $b is a 'hard' reference $c = $b; # $c is a 'symbolic' reference?
Is this correct? The perlref docs say that a symbolic ref are names of other variables. So in the case above, is $c a symbolic ref because it merely holds as its value another variable that is a hard ref. Or is $c just a deeper hard ref?

2. I looked up 'strict' in the Camel book and it said: "If no import list is given to use 'strict;', all possible restrictions upon unsafe Perl constructs are imposed." My question is: What exactly is an unsafe construct, and what is it that makes it unsafe?(OK that's 2 questions...sorry)

I'm trying to better understand why 'strict' is safer. I use it all the time and the code I write is usually "safe", but I don't know why it would be unsafe.

Thanks for all your help.

Amel - f.k.a. - kel
