Note also that if you *do* want syntax-error, it might be better to report error location more specifically that the entire cond.For misuses like (cond) and (cond 1) it makes sense to report the entire macro call.
That is easy, since define-syntax-case allows a fall-back case: (define-syntax-case cond () ((_ c1 c2 ...) ...) (x (syntax-error "cond has invalid clause list" #'x))) For other errors I'd want the error attached to a specific clause: (syntax-case c1 (=>) [...] [ce (syntax-error "cond has invalid clause" c1)]) Then the error message refers to the specific clause. -- --Per Bothner per@xxxxxxxxxxx http://per.bothner.com/
