[section:add_const add_const]

   template <class T>
   struct add_const
   {
      typedef __below type;
   };
  
__type The same type as `T const` for all `T`.  

__std_ref 3.9.3.

__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_const.hpp>` or ` #include <boost/type_traits.hpp>`
