No, we'd implement the necessary type computations to make result_of
work. Remember, result_of takes types as inputs, not objects.


   result_of<bind_(std::minus<int>, int, _1_)>::type

just requires that bind_ know about the types produced by boost::bind.
And in

   result_of<minus_(int, _1_)>::type

minus_ would just have to know how the operator- in the lambda library
