This book is the most awesome resource on Perl I have ever found. I just finished reading it through for the second time; it was a good read when I was a beginner, and it is still a good reader as an advanced programmer.
Ultimately, it doesn't matter what scripting language you use.
Perl, Python, R, Javascript, Ruby (ok, maybe not Ruby), whatever. Having your code be lucid, literate and readable is important no matter what language.
If you work in Perl, this is a great book to help make your code more idiomatic (or, as Perl coders say, "Perlish").
This is one of the two books (along with The Camel) I have at my elbow every time I code in Perl.
The book context was good. As a professional Perl programmer I did find some information useful.
However, I purchased this for my eReader as a quick reference and the code samples are extremely hard to read. I am disappointed in the eReader version of this book.
A second edition?? The first one was brilliant. Before I've even finished chapter one of the new edition, I've been introduced to the goatse operator... it's the slightly-unhinged quality of the language that gives it that distinct Bukowski flavor.
