Title: The best treatment of this complex subject I've ever found!
Review: Short of a brain transplant from Jon Orwant himself, this text book and the accompanying online interactive course is the best possible way to learn this subject. I would have forked over $100s of dollars for a similar classroom training course and still not learned it as well as this book and course taught me. As a busy computer professional, I can't imagine any other more efficient way of learning a subject. If you want or need to learn Perl --- Buy this book
