13.4 Object-Oriented Programming

Object-oriented programming is a style of program design that provides a well-defined interface to data and subroutines (called methods in "OO-speak"). It's not hard to learn; it makes some things easy that would otherwise be hard (and vice versa, but you don't have to use it for everything!). A great deal of Perl code has been written in object-oriented style since the capability was added to the language a few years ago.
