Très bon début avant d'attaquer Perl Best Pratices et Intermediate Perl.
Venant du C, c'est un choc de découvrir un outil qui semble faire l'effort d’interpréter au mieux ce que cherche à mettre en place le développeur. C'est un grand choc pour moi et une révolution. Ma seule crainte est d'avoir à présent du mal à retourner vers des langages moins intelligents.

1. The book is not intended to the ones who have no programming experience at all. The read should be at least an intermediate programmer, because the basic programming concepts of the language (Variables, Subs and etc..) are badly explained.
2. Because of Perl's C Like Syntax, it is recommended that the reader will know C, Awk, or Grep and Some experience in the Unix Environment.
3. The Book itself is badly organized, certain complicated things are shown in examples and explanations, and those things are taught many pages afterwards. For Example: An Example of a perl program is shown on page 10, and that example contains subs and pattern matching, which are taught 100 Pages later!
These are the 3 Main Disadvantages. For Conclusion, if you're new to programming, or want to learn Perl easliy, buy "Learning Perl", but if you're a somewhat experienced programmer, and want to master Perl, this book is the best one you'll find for that purpose.
This book is intended to serve as a reference as it tackles the more complicated aspects of Perl. If you start learning Perl with this book, then you will find it a very difficult language to graps. However, I do not want to take anything away from this book. This book is fantastic for those who want to dive into Perl a bit more and have passed the beginners level. I purchased both the books and once I had finished reading the Learning Perl book, I started turning to this book to get a better understanding of things, especially regular expressions.
But ... somewhere in the extensive revisions, additions, extensions, and deletions that transformed the first Camel book into this, the second Camel book, the magic went away. And some very suspicious stuff went in. The book lost its digressive, essayic feel and became more of a perfunctory reference work. Additionally, some of the completely new material turned out to be just a little ... strange. The discussion of object-oriented programming based around the term "thingy" just doesn't do it for me. (Ignore all that and read Damian Conway's book instead.)
Preferences of style and tone aside, an unavoidable flaw of an infrequently-updated book like this one is that it inevitably refers to an obsolescent version of Perl. If you want current Perl documentation, you need to read the man(ual) pages that came with that version of Perl. What's in this book is generally but not completely accurate for newer versions of Perl. And because it's intended to be a more or less complete reference covering even small details, it can't help but be dead wrong on some points as the language continues to evolve. Bear in mind, also, that much of the material in this book comes STRAIGHT from the man pages. (Just not the up-to-date versions.)
A third edition is in the works, which will no doubt be at least a temporary improvement. If the newer version restores the insight and charm of the original, it will certainly deserve a place on your programming bookshelf. But as a reference work intended to cover a constantly-evolving language, Programming Perl will always suffer by being out of date.
If you are the type who dislikes reading electronic documentation, by all means, buy a copy of this book. But you'll find that you have to use the online documentation anyway.
To make a long story short, the book is excellent. Going from overview to the gory details (actual section name) with clear examples. The book serves two main goals in my opinion: 1- Introduce the Perl language and eco system, 2- act as a quick reference.
If you are starting off with Perl, or thrown into it like me, you cannot go wrong with this book. It will save you a lot of time searching around the web. Buy this book.
But don't let the name fool you: This book is not the place to learn Perl, as I found the hard way. It just simply assumes too much knowledge on the part of the reader, and has a horrendous paucity of example code. If Perl is something you are going to explore and use to a great extent, "Programming Perl" will eventually become indispensible to you, I am certain. But if you are new to the language: DANGER! DANGER! ABUNAI!
All things considered, I would give it four stars -- five for its breadth of coverage minus one for its poor organization. But the book's title implies that it is meant as an introduction to Perl, but an introduction it just ain't! The authors say as much themselves in their introduction, but I think the unsuspecting novice deserves to see it on the front cover too. So I am taking away one more star for a total of three.
"Programming Perl": a great reference, a horrid learning tool.
