Learning Perl objects, references, and modules

Object-oriented language for others. It is used for everything from performing quick global replacements on text files to crunching huge, complex sets of scientific data that take weeks to process. Perl is what you make of it, but regardless of what you use Perl for, this book helps you do it more effectively, efficiently, and elegantly. Learning Perl Objects, References, and Modules is about learning to use Perl as a programming language, not just a scripting language. This is the book.
