Maybe because we're missing a type trait

template <class T>
class add_const_to_value;

that can be used like this

template <class Pointer>
void foo(typename add_const_to_value<Pointer>::type pointer_to_const_object);

Maybe because constness of pointers/objects is not a generally well understood 
topic.
