Is there anything like struct-copy that works to functionally update a field value in a structure, where the field happens to be defined in the super-type? In the example below, I want to "functionally update" a field of the sub structure inherited from the base definition...
(struct base (a b) #:transparent) (struct sub base (c) #:transparent) (define S (sub 1 2 3)) (struct-copy sub S [c 4]) ; works ; doesn't work: (struct-copy sub S [b 4]) (struct-copy base S [b 4]) ; produces a base, not sub Thanks in advance, --- nadeem _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/users
