4 out of 5 stars!
A very well laid out book, with plenty of examples for the novice-intermediate perl programmer. I've deducted one star simply because of the age of the book (published in 2001, it would be nice to see this volume updated), but that shouldn't put you off trying to get a copy.
The first four chapters give useful information on programming defensively - plus avoiding common perl pitfalls. Chapters 5 & 6 are gems, providing great introductions to tracing and testing your code. I found these chapters excellent.
Even though the title of the book is Perl Debugged, the debugger isn't actually covered in any great detail until nearly half way through the book at chapter 7. The authors give you a useful introduction to using this tool, plus covering some details like emacs and ptkdb.
Chapters 8 - 11 outline some common errors that can occur in your code, plus methods for fixing them. Chapter 12 outlines some differences between perl and other programming languages.
Chapter 13 - Debugging CGI Programs - another gem, provides useful information on the same.

This is a great little book (262 pages), and contains many useful code snippets and real world examples. The authors style is humorous and informative, and they dont simply rehash the perl documentation like other writers. One of this books authors, Peter Scott, also wrote the very good Perl Medic: Transforming Legacy Code by Peter J. Scott, and while there is a small bit of overlap between the two books, they do seem to compliment each other nicely.
