Which is where I thought it was left earlier...? :-)
And it's not just what the macro/function syntax will look like,
but also how these will play into a more generalized expression
handling mechanism.  Defining something one-off now that doesn't
fit well into a long term plan is less than ideal.

Yes, I know that is tantamount to requiring the whole, larger
picture be solved first.  But Dave is right -- at least an outline
of the direction.  Seriously, the lexical problems can form some
of the nastiest gotchas if we're not careful from the onset.

Exactly.

Only if they are in Austin. :-)  Which is to say "Sorry, no."
