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.
