Ladislav, are you familiar with the old American (advertising)

Well, considering the following:

Executed

Also evaluated!
I'd draw a slightly different conclusion:
Unevaluated REBOL functions (such as the result of evaluating
'func, or the result of 'get on a word which is bound to a
function) have no printable representation.
The effect of evaluating a REBOL function (as when evaluating
a word which is bound to a function, or when evaluating 'do
with a function value as its argument) depends on the content
of the function's body.
Thoughts?
