--- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> ---
For Barry's example clang prints:

g.C:5:8: error: use of undeclared identifier 'B'; did you mean 'A::B'?
void f(B::X x, int j) {
       ^
       A::B
g.C:1:14: note: 'A::B' declared here
namespace A::B {
             ^
1 error generated.


This is much better. Ideal even.
