Well, a singleton can hide and/or protect its private data.

Actually, a unit is a singleton. The procedures are the methodes, the =

interface declares the public methode and the implementation the private =

methods. The constructor is the initialization section and the destructor =

the finalization section.

But, in pure OOP the unit concept does not exist. I interpret the =

singleton as the OOP equivalent of the unit.
