If you've been using Perl for more than a year and you find yourself dealing with increasingly complex data structures, you probably need to get and read this book. It lays out tricks and techniques for storing, manipulating and using deeply layered hashes, arrays, anonymous entities and even references to subroutines. This book is clearly written, full of excellent and illuminating examples, peppered with exercises (and illustrations of possible answers to same) and even amusing now and then. There are a few errors to be found, but errata lists are available from the O'Reilly website so you can be edit them out yourself before you even read it. I review a chapter of this book weekly, and it has dramatically improved my productivity as a Perl programmer. As the title of this review says, this book is indispensable.Was this review helpful?
