 More than objects, but a wee bit long in the tooth now
This is a fine book, but the passage of time has rendered some parts of it less relevant.
As an introduction to object oriented programming, and how to do it in Perl, this is one of the best sources you could learn from. Neither The Alpaca nor The Camel do such a good job.
And it's not just objects that are well covered. You'll also find lucid explanations of closures, type globs, the symbol table and tied variables, all of which can be considered advanced Perl.
Elsewhere, though, the material has not aged so well, superseded by the author's own Perl Best Practices, where some of the recommendations have been reversed, or improved upon ('inside out' classes, for example, as implemented in Class::Std, is a superior development of the flyweight approach mentioned in this book). Some of the material, which concentrates on CPAN modules, and the experimental pseudohashes is not so useful in the light of this - the latter are on course to be removed in Perl 5.10. The sections on building objects using references to things other than hashes (e.g. arrays, regular expressions and subroutines) is clever, but this reader was unconvinced of their utility.
There's also coverage of generics, although in Perl this is not much like generics in C# or Java, basically passing around Perl code as uninterpolated text strings and then evaling it inside a subroutine, where any lexical values are interpolated.
Finally, there are chapters on multimethods (no more elegant or manageable in Perl than other languages that support this feature, alas) and persistence.
The principles discussed remain relevant, and the book is a pleasure to read. However, if you already familiar with OOP and just want to get going as fast as possible, the relevant chapters of Intermediate Perl and Perl Best Practices might be better places to look.
 Amazing style and clarity
I am a newbie to perl and I'm writing an application that involves using object-oriented perl. I have not seen any other book that explains difficult concepts with amazing clarity that even a newbie like me can understand. I wish other perl books were written as simple and clear like this one :(
An excellent catch all
I have written a number of modules for Perl over the last 5 years, and I really wish I had bought this book earlier.
It is a mixture of sound coding practices and great examples. I actually bought this after reading Perl Best Practices by the same author, and have not been disappointed.
This is a book written by someone how obviously knows Perl from the inside, and can apply this to real world issues.
The first useful documentation on Perl OOP
This is my favorite Perl book, alongside Advanced Perl Programming.
When I first read it, I was very upset that 3 pages in particular had not simply been inserted into the original Camel book, which I think is one of the most important yet most poorly written programming books ever.
I wish Damien Conway had written Camel and Llama.
A Must-read Advanced Perl Book, the title is misleading
I almost passed this book by, thinking it was a primer into the OO world with Perl. I'm comfortable (if slightly annoyed) writing OO Perl code. What surprised about Conways text was that the book used OO as a premise to instruct the reader on more advanced aspects of Perl; its more an Advanced Perl book than the expected Object Oriented book.
I learned more depth of Perl than I have in years. Perl is a thick and crafty language. Chapter 2, subtitled "A Perl Refresher", was worth the price of admission alone, as he deftly re-hashed Perl features he would use later in the book. The practices and features of Perl he later expanded on in the OO chapters incontinued to impress me.
If you are a Perl programmer, beginner to advanced, this is a must-read book, and a great source of coding inpiration. It made me a better programmer, in Perl and other languages.
This book is was published in 2000, and usually the half-life of most computer texts don't hold up 5 years, but this book certainly does! Also, I just noticed Conway just published "Perl Best Practices" which I am eager to tackle.
