-----------------------------------------------------------------+----------
 boost::reference_wrapper lacks the ability to forward calls the referenced
 type's operator(), e.g.:

 {{{#!c++
 #include <boost/ref.hpp>
 #include <functional>
 #include <iostream>

 int main()
 {
   auto f = [] { std::cout << "Here" << std::endl; };
   //auto rf = boost::ref(f); //No operator() overload.
   auto rf = std::ref(f);

   f();
   rf();

   return 0;
 }
 }}}

 There are a few other related differences with the standard, e.g.
 std::reference_wrapper inherits from std::{binary|unary}_function, may
 have value_type, etc.
