Bug (?) in namespaces and overloading resolution

Can you be a bit more specific why you think this should work? It
seems you are aiming at argument-dependent lookup. Given the arguments
cerr of type std::ostream (in theory) and t of type A::X, the
associated namespaces of this call are std and A. Neither one defines
a suitable operator; it doesn't help that one is defined in B.

So AFAICT, the diagnosis is right.
