   Unfortunately the latter won't work, because 'std::setw' does describe a   
   function and not a function object type.   
      
   Technically it would be possible to take advantage of result_of by   
   rewriting this to   
      
   std::result_of::type;   
      
   but then you would still depend on decltype again.
