Comment (by giecrilj@…):

 It is unwise for `mem_fn` to define `result_type` at all.  The type of the
 member need not even be copyable.  Instead, it should be arranged so that
   * `boost:: result_of < F (U &) >:: type` be `type_of_the_member &`
   * `boost:: result_of < F (U const &) >:: type` be `type_of_the_member
 const &`
