|There's more than one way to do things|
If I were a total beginner and I needed to know how to create an object, after this example I would be able to go through my first module.
However, if I were a total beginner, I would be also totally ignorant about objects and what they are.
More specifically, if I were a total beginner, I would be used to work with numbers in this way:
Therefore I would be more than puzzled with your example that changes my way of dealing with numbers from $n += 3 to $obj->add(3) without any visible benefit for this additional burden.
So, if I were a total beginner, from your example I would probably learn what to do, but not why.
What I am getting at is that Object Oriented programming is supposed to make things easier for the programmer, not more difficult. The purpose of OOP is to imitate reality. That's why there are objects. SO your example would have been more attractive if you were talking about something we can see and touch, such as cars or books.
There are some better examples available in the Monastery. Have a look at our Tutorials section.
Also, your example would look much bettere if it was properly formatted. Consider using perltidy, or some smart editor.
