Ok, I've made changes like:

(define-syntax ___
  (syntax-rules ()
    ((_ expr ...)
     (syntax-error "___ outside of pattern"))))

to the original match/match.scm.
And added all the new syntax I've defined to the exports for the Guile
module, and it's still passing all the tests,
So are there some new tests I can add to make sure these changes are
having their intended effect?
