Uhm, try:

(print (match '(lambda (a b) (+ a b))
              ((_ llist body ...) #t)))

Ellipsis do somehow not match at all.

I tried these days to either get the old match working or something

ellipsis (which makes me wonder why I should use "match" at all for the
remaining effect.  So I'm not satisfied with the approach.
