Ok, this doesn't work because you are trying to value initialize a reference.
A small workaround:
namespace detail
       {
           template <typename T> T make();
       }
// ...
               template<class Sig>  struct result;
               template
               struct result{
                   typedef
                       decltype(cos(eval(detail::make<Arg>(),
detail::make<Cont>())))
                       type;
               };
      // ...
Or use boost::declval
