Perl 6 Now: The Core Ideas Illustrated with Perl 5 Upplaga 1

This book is a guide to Perl 6 language features, as well as an advanced teaching guide for Perl 5. It’s the most up-to-date Perl book available. Examples are provided for both Perl 5 when using modules to back port Perl 6 features, and Perl 6 native examples. This book’s pragmatic approach shows you how to bootstrap new features onto the code you write day-to-day.

Perl 5 has long been missing important features but no agreement could be reached on the form they should take in the language, or even if they should be included. The announcement of the Perl 6 project has spurred development of Perl 5. As features are accepted into the Perl 6 design and Larry Wall finalizes the form it will take, many features are being added back into Perl 5. Perl 5.9, with opinional extensions from CPAN, hardly resembles the original Perl 5 language that first came out 9 years ago. Modern Perl is cleaner, more helpful, less error prone, more expressive, more scalable, and better suited to what people want to do in this day and age.
