[section:add_pointer add_pointer]

   template <class T>
   struct add_pointer
   {
      typedef __below type;
   };
  
__type The same type as `remove_reference<T>::type*`.  

The rationale for this template
is that it produces the same type as `TYPEOF(&t)`, 
where `t` is an object of type `T`.

__std_ref 8.3.1.

__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.

__header ` #include <boost/type_traits/add_pointer.hpp>` or ` #include <boost/type_traits.hpp>`
