[REBOL] REBOL just a programming language? (was local vars in functions)

No doubt you are referring to the sequence:
func [...] [...]
Which bit is the actual function?
(a) the first bit
(b) the second bit
(c) the third bit
(d) all of the above
(e) none of the above
My preference is for answer (e) however I recognise that it is convenient to
talk as if it were (d).
But your suggestion of the double colon to indicate "local" variables gives
the feeling it might be (c).
What if I changed this to:
func [...] relative-expression
where relative-expression is a word set to a value of type block!
So now, if relative-expression (the block) defined what was local and what
was global would it still be relative?
Relative to what?!
- I think that question is the answer to the
mystery/purpose of REBOL. :^)
My obscure position is that the first block defines what in the second block
will *become* bound to the function context and that this usage is closely
related to the fundamental design of the REBOL.
