The most notable thing about Object Oriented Perl is Conway's excellent perspective on object-oriented concepts and how they are implemented in Perl. This book does a remarkable job of cutting through traditional jargon and illustrating how basic object-oriented design techniques are handled in Perl. (A useful appendix attests to the author's wide-ranging knowledge, with a comparison of Smalltalk, Eiffel, C++, and Java with Perl, including a summary of object-oriented syntax for each.) This book also features a truly excellent review of basic Perl syntax.

Throughout this text, the author shows you the basics of solid object design (illustrated using classes that model music CDs). Basic concepts like inheritance and polymorphism get thorough and clear coverage. The book also points out common mistakes and provides many tips for navigating the powerful and flexible (yet sometimes tricky) nuances of using Perl objects. For instance, Conway shows how to achieve true data encapsulation in Perl (which generally allows calls across modules) as well as its natural support for generic programming techniques.

Filled with syntactic tips and tricks, Object Oriented Perl is a sure bet for any programmer who wants to learn how to use Perl objects effectively. --Richard Dragan
