Class::DBI is currently number one in my list. It brought back the job of programming.
Date::Calc makes me hate current date/time system in use a little less. Sometimes I still wonder though, why not devide a year into a proper number like a 100 or 128. :)
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).
