Also note, the kind of a name introduced by a using-declaration is the
same as the kind of name to which it refers; e.g. a using-declaration
that names a class introduces a class-name into the scope where the
using-declaration appears. Example:
namespace N {
int A;
template <class T> struct B;
}
struct A;
using N::A; // Ok
int B();
using N::B; // Error
