[section:add_rvalue_reference add_rvalue_reference]

   template <class T>
   struct add_rvalue_reference
   {
      typedef __below type;
   };
   
   template <class T> using add_rvalue_reference_t = typename add_rvalue_reference<T>::type; // C++11 and above

__type If `T` names an object or function type then the member typedef type
shall name `T&&`; otherwise, type shall name `T`. ['\[Note: This rule reflects
the semantics of reference collapsing. For example, when a type `T` names
a type U&, the type `add_rvalue_reference<T>::type` is not an rvalue
reference. -end note\]].

__std_ref 20.7.6.2.
