This series of articles on developerWorks comprises a complete guide to better programming in Perl. In this fifth installment, Teodor explains what Object Oriented Programming is, when to use it, and how it works in Perl. Object Oriented Programming (OOP) is a powerful programming technique, but it is not a panacea. Good programmers must understand how to use it, and must also know when to rely on more traditional programming techniques. Using OOP in Perl is easy. Unlike more restrictive OOP languages like C++ and Java, OOP in Perl places very few arbitrary constraints on the programmer. OOP is an essential addition to every programmer's toolkit, and a very useful technique for expanding the range of problems that may be solved with Perl.
