I think there's no way to do that, assuming that you want a single constructor that answers #t to `struct-constructor-procedure?`. If you get to substitute a function for the constructor, then you could make that function use `procedure-reduce-arity` on each raw instance, or you could generate a structure subtype for each arity and instantiate a subtype based on field values. ____________________ Racket Users list: http://lists.racket-lang.org/users
