Don't think it was April 1st when I looked at the website
But I'm sure that the Apress website had some sort of 'programming for people who haven't programmed before, using Perl as the language' book in their forthcoming titles section. Maybe they thought better of it, but I would have been inclined to buy that one just to see exactly how they did it. The phrase 'for the love of God, Nooooooooooooooooooooooooooooooooo!' springs to mind somehow. Coming next, 'Chainsaws for Toddlers'.
