Intermediate Perl is about making the leap from things that are easy to hard. Originally released in 2003 as Learning Perl Objects, References, and Modules and revised and updated for Perl 5.8, this book offers a gentle but thorough introduction to intermediate programming in Perl. Topics include: Packages and namespaces References and scoping Manipulating complex data structures object-oriented programming Writing and using modules Testing Perl code Contributing to CPAN After the successful format of Learning Perl, we designed each chapter in the book to be small enough to be read only in one or two hours, ending with a series of exercises to help you practice what you've learned. But regardless of what you use for Perl, this book helps you do more effective, efficient, and elegant. Intermediate Perl is about learning to use Perl as a programming language, and not just a scripting language. This is a book that turns amateur Perl into Perl programmer.
