So, I have a dict A that looks like (list ("string as key" . (lambda
(arg) ...) ...)I do ((dict-ref A key (lambda (_) "wrong key")) some-params). When keys are valid the above work as expected. When the key does not find any, I was expecting ((lambda (_) "wrong key") some-params) but it fails with this msg: arity mismatch; the expected number of arguments does not match the given number expected: 1 given: 0 Upon further inspection, (dict-ref A key (lambda (_) "wrong key")) does not seem to return the lambda but seems to invoke it. Why so? What am I failing to understand here? Confused, jGc ____________________ Racket Users list: http://lists.racket-lang.org/users
