Hi, exactly! To me that's the biggest difference. Rebol doesn't the
concept of a scope. A block can have a mix of words from different
contexts. There is no need that all words are in the same "scope". To me
a word! is a key into a lookup table to get a surrogat for it. This
surrogat is looked up again etc. until a terminal symbol is reached.
