I never said it would be faster. Indeed, I would completely
abandon that syntax, and use a value based grammar, so that a
block parser can be used.

That's the easy part. :-)

Again, I agree, but you can't expect LOAD to be able to convert
into REBOL values any kind of syntax "magically"; also, you cannot
expect to be able to do value base parsing if your grammar is not

Hmm, I think that it would be much simpler to design a value based
language. :-) Or, use string parsing with a simple rule that only
converts you language into REBOL values, and then use block
parsing for the real parsing.
