@ -158,9 +158,9 @@ The @racket[#:prefab] option obtains a @techlink{prefab} (pre-defined,
globally shared) structure type, as opposed to creating a new
structure type. Such a structure type is inherently transparent and
cannot have a guard or properties, so using @racket[#:prefab] with
@racket[#:transparent], @racket[#:inspector], @racket[#:guard], or
@racket[#:property] is a syntax error. If a supertype is specified, it
must also be a @tech{prefab} structure type.
