As I understand it, objects are exactly the opposite of functional programming,
in that they encapsulate state, and functional programming wants to avoid
state (variables, if you want).

Ah. You just replace methods by objects.
You should be programming Java:
I prefer imperative programming. (verbs, if you want).
It comes more natural.
Well, each his own style. But, if you allow me: the post on the lazarus
forum and the Xavier page should really explain what you mean by OOP. I
guess most people will be confused, as I am.
Thanks for explaining.
