% On the other hand, consider the possibility that 'object-oriented'
% is just the current fashionable brand of snake oil.  Like 'lateral
% thinking', 'right-brain thinking', 'egoless programming', and the
% hula hoop.

   Consider the articles "Using Types and Inheritance in Object-Oriented 
   Programming" (IEEE Software, September 1987, pages 71-79 -- a tutorial) 
   and especially "Designing Families of Data Types Using Exemplars" (ACM 
   Transactions on Programming Languages and Systems, April 1989 -- advanced
   topics) to see that this is not the case.  It just takes a little
   getting used to.  The object-based (ADT) paradigm is only a special 
   case of the more general (and more powerful) object-oriented paradigm.
