> This misses the point. By using `with` I can instruct the compiler that I don't want my program not to compile if I add or remove fields. In the current system I can do this with any update I want to make to a record except if for some strange reason that update happen to touch all the current fields of the record.  

I don't particularly wish to argue for or against using this warning, but I think it is worth noting
that this is not really any different from:

  # type t = Foo | Bar;;
  type t = Foo | Bar

  # let f = function
    | Foo -> 1
    | Bar -> 2
    | _ -> 3;;
        Characters 47-48:
      | _ -> 3;;
        ^
  Warning 11: this match case is unused.
  val f : t -> int = <fun>

Regards,

Leo
