"Last month, we started looking at Perl, the "Pathologically Eclectic Rubbish Lister," mostly sticking to the very basics. This month, we'll cover a more advanced topic."
"Perl is not the first language that pops into my mind when someone says "object-oriented," or even a close runner-up, but it is entirely possible to write object-oriented code in Perl. The subject is introduced in the perlobj man page with three rules:
1.An object is simply a reference that happens to know which class it belongs to.
2.A class is simply a package that happens to provide methods to deal with object references.
3.A method is simply a subroutine that expects an object reference (or a package name, for class methods) as the first argument."
"To make sense of this, you first need to know about references, packages, and subroutines."
