Oh my gosh, Randal, I thought it was just me you gave invalid advice to; but clearly you've been doing it for years.
Your track record of providing plain wrong advice, then telling everyone not to question you because of your Perl history, is exactly why I would never purchase a book that you've written. Moreover, I would highly recommend any newbie to steer well clear of you for fear of almost guaranteed bad advice.
Randal, please please please work on improving your Perl and general programming skills and stop publishing in the name of making the Perl world a better place. Come back when you've become a better man.
