Oh-oh!  You hit one of my favorite subjects!  As some of you
know, I'm a great fan of OO design and programming.  But I've
always believed that OO is best appreciated using a language
specifically designed for the purpose, such as Java or
Smalltalk.  Hybrid languages like C++ tend to be a bit of a
mess.

On the other hand, with a bit of care, OO techniques can be
applied in any language.  I'm sure most people would agree
that learning an OO language can make you a better programmer
even when using a non-OO language like RPG.

Will we ever have an OO-RPG?  I don't know.  My biggest worry
is that if we ever decided to do it, it would be unnecessarily
over-designed.  Furthermore, to do OO properly in any hybrid
language really requires a great deal of discipline on the
part of the programmers, which leads back to my point that
learning OO is best done using an OO language.

Cheers!  Hans
