The Force will be with you; always.
== unset!

== unset!
Both 'print and 'write return a unset! value, which can't be "assigned" as a
value to 'Fred, by the set-word "Fred:". Perhaps 'attempt from the latest
Rebol/Core might be more useful to you:
>> source attempt
attempt: func [
{Tries to evaluate and returns result or NONE on error.}
value
][
if not error? set/any 'value try :value [get/any 'value]
]
I hope that helps!
