[PATCH] D30848: Implement DR 373 "Lookup on namespace qualified name in using-directive"

[Richard Smith via Phabricator via cfe-commits]

rsmith added a comment.

Functionally, this looks good. How do the diagnostics look in the case where lookup only finds a non-namespace name? Eg,

  struct A { struct B {}; };
  namespace X = A::B;
