"Just the FAQs: Coping with
Scoping," an article by Mark-Jason Dominus
about how Perl handles variables and namespaces, and the difference
between use vars( ) and my( ):
It's important to know how to perform
handling in Perl code. Exception handling is a general Perl
technique; it's not mod_perl-specific. Further
information is available in the documentation for the following
Error.pm, by Graham Barr.
Devel::StackTrace, by Dave Rolsky.
Try.pm, by Tony Olekshy, available at https://www.avrasoft.com/perl6/try6-ref5.txt.
There is also a great deal of information concerning error handling
in the mod_perl online documentation (e.g., https://perl.apache.org/docs/general/perl_reference/perl_reference.html).
Perl Module Mechanics: https://world.std.com/~swmcd/steven/perl/module_mechanics.html.
This page describes the mechanics of creating, compiling, releasing,
and maintaining Perl modules, which any mod_perl developer planning
on sharing code with others will find useful.
