IIRC, Ladislav Mecir created methods.r some time ago? It allowed you to have
classes, objects, methods, etc. IIRC ... I just wonder, if it is still available
anywhere? :-)
On the other hand - I programmed in CA Visual Objects. I read many papers on
object orientation, and while I am not too good programmer, I sometimes don't
fully understand all the fuss about object orientation and its advantages - hey,
the result is some executable code, user doesn't care, so the only one question
is - programmer's efficiency.
With Rebol, you get nice space navigation, you have very dynamic binding on
demand. So, if I understand things correctly, you have much wider freedom to
define things exactly as they fit your solution. btw: as of Core 2.5, object
creation functionality was slightly extended - although I never found practical
reason to use it :-)

Would be nice to have. I just wonder what happened to Carl's Rebol/Author ....

Debugger ...would be helpfull ...

But reusability as you describe it, has very low in common with object
orientation itself imo. The topic ran here several times already. The Rebol
script header contains 'needs field, so the idea was that once you do
%some-script.r, and its header contains Needs:
[http://rlibrary.com/gfx/effects.r 1.2], it would look for it locally, and if
not available, script would try to download it from the library ...
Another usefull thing would be probably to extend help to work upon objects - to
autocollect help info from it's functions, print list of words and their values,
etc.
What would I like to see maybe even more, - more dialects ...
