"In this article we continue to talk about the essential Perl basics, that you should know before starting to program for mod_perl."

"Sometimes it's very hard to understand what a warning is complaining about. You see the source code, but you cannot understand why some specific snippet produces that warning. The mystery often results from the fact that the code can be called from different places if it's located inside a subroutine."

"...It's a known fact, that one cannot become a Perl hacker and especially mod_perl hacker without knowing how to read Perl documentation and search through it. Books are good, but an easily accessible and searchable Perl reference at your fingertips is a great time saver. It always has the up-to-date information for the version of perl you're using."
