I guess its my turn to feel a little dumb (no pun intented ;-) I can see it

Ah, then you mean I've been lucky, in general, for the last 2 years ':-D
damn!
well, thanks for the pointer... it ain't that obvious because when you probe
objects... it leads one to think that the structure is not as relevent as in
other languages. I really thought that the object structure was more
dynamic...

[...].
What led me to use "make object! [...]" was that the following code
returns an error (in rebol/view)!
--------------------------
rebol []
myfeel: make feel []
** Script Error: feel has no value
** Where: do-boot
** Near: myfeel: make feel []
-----------------------------------
Although I have now cloning the feel object from other Faces... I think it
would be nice that the docs mention how to do it explicitely... since the
docs do take the time to talk about the feel object ... just a short example
like:
myface: make face []
myface/feel: make myface/feel [] (creates a clone of the default feel
created by make face)
Can you then confirm or infirm the following sentence?:
objects are static contexts, contrary to the global context which is
dynamic
Thanks!

PS: I still think the doc should be modified as I explained... it might help
someone else to keep from doing the same mistake.
