Yes, that is a succinct demonstration of the difference between ALIAS
and SET, but my question was "Why do we need that capability?" Maybe
I can ask it differently, in two stages:
1) When is the last time anyone on this list used ALIAS for anything?
(other than demonstrating what ALIAS does ;-)
2) Could that need have been served by some other mechanism already
in REBOL? (such as SET/PROTECT or passing a reference)
As for myself, the answer to question (1) is "never" but perhaps
someone here can enlighten me as to what I've been missing.
