One recent thread on the list insisted on the fact that nothing in rebol can be
evaluated correctly outside of its original context (if I understood correctly).
So reading your answer I wonder if this applies to objects printed with 'mold ?
Is it possible for such objects to contain a different content when loaded back
into a different context than the one they were "saved" from ?
And if this possible context "confusion" exists is there any way to make sure
that objects are saved along with all the necessary context ?
Note that I am not writing any code related to the subject, I am just curious ;)
Also I did not manage to see what was exactly the difference beetween doing "do
load mold/all" and simply doing "do load mold" in your example.
Both seems to produce the same result, so what benefit does the /all exactly
bring in that case ?
Best regards,
