But ##sys#unbound-in-eval is defined only when eval'ing, not for
compiled code, and not even when I put the test code into a file and
"csi file.scm".

(use lolevel)
(define (handler . args) (printf "something called with ~a; unbound
~a~%" args ##sys#unbound-in-eval))
(unbound-variable-value handler)
