A first, a joke:
((i-have-spare day ...)
(hack 'macros (day ....))))
So we have recursive macros expanding recursively, as they should.
I was working on macros with ellipsis almost whole week i. I was
changing approach several times. But it looks like flat ellipses (not
nested) work well.
All most important parts of macros are SyntaxRule.match method, or
rather matchr, and W_Transformer.substitute.
They raise exception when discover ellipsis to handle it at higher level.
matchr is kinda handling nested ellipses, but substitute not yet.
That's pretty it.
I would like to get nested ellipses working and then start playing
with continuations. Wish me luck.
