Hi,

Mathematica is a functional logic programming language and not
a object oriented. 
You can't ask how to make LISP or Prolog object oriented. It is
still possible to make some object oriented definitions but it
is not the "natural" way.

When every thing is an expression it is useless 
to introduce objects because the most general construct
is already build in.

The Mathematica Programmer II has some pages how to fake object oriented
programming with Mathematica. It was original a part of his lectures on
Computer Science.


Hope that helps
  Jens
