Hi Michael, I'm joining this thread late. First of all I'd like to note that I found the original article (maybe it's more of a blog post) on O'ReillyNet, which I only skimmed, to be mostly factual, and correct and I'm saying this as an active Perl programmer and contributor to the Perl ecosystem (including the Perl core and CPAN - https://metacpan.org/author/SHLOMIF ) who knows a little about the proper way to do things and been helping or trying to help people with their Perl problems on various Perl-specific forums. Otherwise, I believe your message was information and insightful. Some nitpicks.
