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, Laurent
