[Pdx-pm] I think that I'm trying to make things too hard.

One way of doing this is:

my $action = CGI::param('action');
eval 'require $action;' && $data->{body} = $action->generate_page();

given that $action contains the name of your module, say 'PageA'.

package PageA;
use strict;
use warnings;

sub generate_page {
    my $class = shift;
   # generate the page here


This has a few holes though, what if the user forces $action to be
something undersirable? what if you forgot to create generate_page? or
if you misspelled it? etc.

You'll be better off by using an existing web framework, like
CGI::Prototype or CGI::Application.
