Type

(all (A B) (-> (list-t A) (-> A (list-t B)) (list-t B)))

Description

Applies function f to each element in the list, then flattens the results by one level. This is equivalent to (list-concat (list-map f xs)).

Examples

(list-map-concat (@list 1 3) (lambda (x) (@list x (iadd x 1))))  ;; => (@list 1 2 3 4)
(list-map-concat (@list 1 2 3) (lambda (x) (@list)))           ;; => (@list)
(list-map-concat (@list (@list 1 2 3) (@list 4 5 6)) list-copy-reverse)    ;; => (@list 3 2 1 6 5 4)
