If you would have used an OO framework like CGI::Application for the structure of your app, you would have been able to do this very easily, without needing to subclass HTML::Template.
package My::App;
use base qw(CGI::Application);
sub load_tmpl {
my $self = shift;
my $template = $self->SUPER::load_tmpl(@_);
# add some global params here
$template->param( ... );
return $template;
}
sub runmode {
my $self = shift;
my $template = $self->load_tmpl('filename.tmpl');
$template->param( ... );
return $template->output;
}
OO doesn't work for everything, but if you find yourself passing the same bits of data to all of your functions, then you probably should at least investigate using an object instead.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
