:) I know it sounds flaky, and might even defeat the purpose for defining
the function element in the first place (ie why don't I just call the global
function directly?) if I didn't think I knew better :). I suppose the real
reason why I'm comfortable with it is that I'm not an OO programmer, I just
borrow OO concepts to improve my programming. Another is that the "global"
functions I am calling aren't used as global - they are only global because
REBOL doesn't suport a module context.
I really just want to separate the definition of the method (function body)
from the object, but I still want the method to be called as part of the
object. Some of these objects can be saved to a file and reloaded, and I
want the function "bound" to the latest definition in the program, not what
the definition was at the time that the object was saved. Also, although I
can't claim to "know" the internals of REBOL, I don't want multiple copies
(or worse, definitions) of the function floating around - it's inefficient.

My objects are dependent on certain function definitions in the program to
make them work - this is by design. I guess, if you are looking at these
from a stricter OO point of view, these are "broken" or "crippled" objects.
The method functions in the program are logically private only to the
associated object. The concept of a "communications object" is new to me,
though. I'll have to meditate on that. I wonder if I can create a single
"melee" object...

You have valid points, well taken. I may be trying to push REBOL into doing
things that it is not designed (well) for.
