Well, often you need to create more than one instance of something. In that case, consider creating a class and instantiating objects of it. OOP is also useful for standardising the interface of your project, and for shortening the amount of code needed to delegate records from one subroutine to another and to export and import functions. Inheritance and role composition give you powerful tools to reuse code and over-ride parts of it. You may wish to read these parts of "The Art of Unix Programming" for some discussion of OOP: * http://www.faqs.org/docs/artu/unix_and_oo.html * http://www.faqs.org/docs/artu/ch14s04.html However, I feel that OOP as it is implemented in C++ leaves a lot to be desired, and that "C++ supports Object Oriented Programming roughly as much as COBOL supports Functional Programming.", and that the way Perl implemented OOP is much better than C++'s. Please read the rest of the resources I've linked to (and other resources online and offline). I'm not saying that you should always use OOP, but it's important to know, and I found it of great utility.
