Add an element to a jquery object
<p>I've got a cached jquery object setup like this</p>

<pre><code>var comments = $('li.comment');
</code></pre>

<p>When creating new elements, is there an easy way to update the <strong>comments</strong> objects instead of redfining it? I'm looking fot something like</p>

<pre><code>comments += $('li.newcomment');
</code></pre>

<p>Is this possible? </p>
