What the heck! Let's just throw away multiply and divide. We don't
*need* them. We can just use add and subtract.
Heck! Why do we need subtract? We can just add negative values.
Hey! Assembler works well without private declarations. Let's just pitch
PHP all together.
The point is that constructs are added to language to assist in the
functionality and maintainability of programs written in that language.
The introduction of private and protected adds to the maintainability
both through its inherent protection capabilities and its clarity of
intent for the maintainer.
Now if PHP could just get polymorphism...
