Then the main module.

use HTML::Template;
use HTML::Entities;

use lib 'code';
use config;

## Security
$CGI::DISABLE_UPLOADS = 1;    # no uploads!
$CGI::POST_MAX = 512*1024;    # max 512k post

sub wrap {

    my $template = templates::loadTemplate('template');
    my %T;
    my $innerTemplate;
    my $q = new CGI;
    my $c;

    $code_ref->({ q => $q,
                  T => \%T,
                  # etc.
                });

     ## Filling in the template here
    if($innerTemplate) {
    # load the template in, put it into %T.
    my $template = templates::loadTemplate('$innerTemplate');
    $template->param($T{innerContent}) if $T{innerContent};
    $T{content} = $template->output();
    }

    print $q->header();
    $template->param(%T);
    print $template->output();

I don't know anything about your template, and I'm not sure what I can deduce from what you've posted. If you want each script to have its own template, then you have to let the wrapped function give that back to the wrapper somehow. You could do this by having a special element in %T or have the wrapped code pass out a hash ref with whatever it wants to supply.

Also, it's important to note that the above code is not tested or anything. When I do this sort of thing myself, I use objects. In that case, I don't go passing things around; the object just sets its own attributes for communication.
