hi, in a macro i'm constructing a lambda-list in the following way:
`(,@rqd-args . ,rest-arg) there are 3 cases: 1. (let ((rqd-args '(a b c)) (rest-arg 'r)) `(,@rqd-args . ,rest-arg)) ==> (a b c . r) 2. (let ((rqd-args '(a b c)) (rest-arg '())) `(,@rqd-args . ,rest-arg)) ==> (a b c) so far so good, nothing special... but: 3. (let ((rqd-args '()) (rest-arg 'r)) `(,@rqd-args . ,rest-arg)) ==> r this is exactly how i hoped it to be, but the question is if this is actually allowed or if it just works "accidentally". r5rs doesn't seem to specify this case and '( . x) is not allowed. i've tried the same expression with guile and sbcl and it worked there as well but i'm still not sure if i should use it. any opinions? tnx&bye, hans. _______________________________________________ Chicken-users mailing list Chicken-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/chicken-users
