Unfortunately, as good as this book is (not only an excellent IDEA for a book that every language should have, but also extremely high-quality code), it's Yet Another Example of the bias Perl has towards Unix systems. In fact, I don't have the book with me right now, but I believe the authors make no hesitation in the introduction of the book that The Cookbook makes no secret about being mostly Unix-based.
I hope and pray that the developers of Perl 6 work towards a more OS-agonostic Perl, and that many more Win32 based (no I mean, REALLY Win32-based, not "Learning Perl on Win32 Systems" :) ORA books come out.
