That's certainly just and true when learning REBOL and I wholly second
that recommendation.
But let me add another angle: In general, scope is always an
illusion
(or an explanatory concept, to use other words) which needs
to be implemented in one way or another. The point where REBOL differs
from most other languages is that you have language-level access to
the "scoping" implementation - via 'bind and friends.
