Fails because:

C++:

     namespace S { namespace T {
         int foo();
         namespace U {
             int foo();
         }
      } }

D:

   extern (C++, S::T) {
       int foo();
       extern (C++, U) {
         int foo();
       }
   }
   foo();  // error, ambiguous, which one?
   S.T.foo(); // S undefined
