Gotta say, I'm not impressed.
The point of my example was to illustrate Perl and jQuery. To that end, I'm intentionally showing how much you can do in a small number of lines of code. I realize JSON and the Template Toolkit are very useful -- I frequently use both for adding features to Bugzilla at work -- but there wasn't any need for them in an example specifically limited to Perl and jQuery.
