Applying this, as I learned this week, is trivial with Moose (or Mouse). Here is a snippet that installs a Template object inside your object, and only when needed, and then dispatches--via the handles param which has even more sugar than shown--any calls on your $object->process to the TT2 object exactly as if it were called instead. It's really very hot.
use Mouse;
has "tt2" => ( is => "ro",
lazy => 1, # not always used
isa => "Template",
default => sub {
require Template;
Template->new();
},
handles => [qw( process )],
);
Update (2017-07-11): moved use to require inside the default sub. A better practice if the object is not always used.

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).
