I didn't know you could do it this way. Neat.
Anyway, TIMTOWTDI, even for Template-Toolkit. Here's the same demo modified to use a filter, which is like a "program" (thus, a sub) you pipe the data through.
#!/usr/bin/perl -w
use strict;
use warnings;
use Template;
my $tt = Template->new(FILTERS => { emphasise => \&emphasise });
my $data = { word => 'callbacks' };
$tt->process(\*DATA, $data) || die $tt->error(), "\n";
sub emphasise {
return "** @_ **";
}
__DATA__
This is a template.
It includes [% word | emphasise %]

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).

or How to display code and escape characters
are good places to start.
