| template <class T> |
| struct add_lvalue_reference |
| { |
| typedef __below type; |
| }; |
| |
| __type If `T` names an object or function type then the member typedef `type` |
| shall name `T&`; otherwise, if `T` names a type ['rvalue reference to U] then |
| the member typedef type shall name `U&`; otherwise, type shall name `T`. |
| |
| __std_ref 20.7.6.2. |
| |
| __compat If the compiler does not support partial specialization of class-templates |
| then this template will compile, but the member `type` will always be the same as |
| type `T` except where __transform_workaround have been applied. |
