  // function for the respective control as the last parameter. Rather than pass a function pointer as
  // the 'transfer' parameter, clients should pass a functor wrapper so that overload resolution is
  // deferred until the actual call. This technique allows this function to serve as an indirect call to
  // a whole set of overloaded transfer functions.
