The @|maker| identifier above matches three kinds of references. The
first kind is any binding whose name has @schemeidfont{make-} in the
middle, and where @|typedef| has a @tech{transformer binding} to
structure information with a full set of mutator bindings; see
@secref["structinfo"]. The second kind is an identifier that itself has a

identifier that has a @racket['constructor-for] @tech{syntax property}
whose value is an identifier with a @tech{transformer binding} to structure
information. A @scheme[_shell-id], meanwhile, must be one of the
