Sorry, I feel very strongly about this. Euphoria is NOT an OOP language, and
should NEVER become so at its core. Using the add on libraries is fine for those
that wish to do so, otherwise get off 'my' procedurals. There are many other
simpler
clearer ways of resorting to solutions rather than resorting to overly complex
and
needlessly obscure object orientated techniques - this is not the spirit of
Euphoria.

Do we not already have that? Admittedly it may not be the catch all that other
languages have, but does it not serve its purpose? Is it not flexible enough
to adapt with a little ingenuity on the part of the programmer?

Again, sorry, I have to disagree. Its not easy to learn, and it adds a totally
unnecessary
level of complexity to any programming task. All of the arguments in favour of
oop can be equally dismissed by any procedural technique. If you want to use
objects
use an OOP language (C++, C#, Delphi, Visual Basic etc etc - Euphoria is not
trying to compete with these - is it?)
