[REBOL] Re: Expression evaluator (an example of parsing blocks)

Hi Russell
Thanks for the corrections. Silly me, I fell into the "negate" trap. I agree
that it would be preferable for REBOL to implement the prefix "-" as a
binary operator, so that it worked like "+", etc. And have the unary "-" be
just no space before a number. IIRC it used to be this way in Core 2.1 or
so. I think there was also some talk at the time of making "+", "*", etc.
work only as infix operators with the prefix versions being "add",
multiply
, etc.
I still wonder if one can always avoid parens with use of both perfix and
infix forms.
Cheers
