Q: A book full of examples of how NOT to write perl . I couldn't resist the title, so I got this book. Unfortunately, I cannot reccommend it to people who want to learn to write better Perl, execpt as a source of examples of the mistakes you should avoid.    For example, in one of the earliest examples, the authors uses "return undef" in a situation where the return value of the routine is assigned to an array, to indicate the routine didn't find any of whatever it was looking for. Unfortunately, this is a mistake, the correct code would be to use "return;" all on its own. The correct solution produces an empty array or interim values; the mistake creates an array containing one element, 'undef'.    There are a number of similar mistakes which indicate the author is in over his head, writing things he doesn't understand; the editors know even less about the matter; and the code was never tested and verified for correctness.    If you want to learn Perl, get "Learning Perl"; If you want to improve your Perl, get "Intermediate Perl.    To

Q: Witty writing, fascinating story...maybe a little whiney . Sean Wilsey is certainly a skilled writer.  I found his writing style insightful, lively, and very funny.  The story of his childhood is jaw-dropping and if it weren't for his wit, this could  be a very uncomfortable story to read.  I enjoyed the suspense Wilsey builds into his story, which can be missing from memoirs.  He leads you along with his child's perspective to keep you turning pages and feel the same jolt he must have felt as a child living through this story.    My only real issue with this book was a nagging question in my mind on how much of it was the author working through his childhood pain and how much was revenge or whining.  Assuming the events described in the book are truthfully presented, I still had a difficult time accepting his parents as complete villains.  As he comes to a mild sort of acceptance of his parents' in the end, I felt I was left out of the journey.    Still, it is a compelling story with lively writing and well worth reading
