I suggest to brainstorm the syntax some more time, because someone could be able

Some seeds:

extern (C++(nspace)) {
     int foo();

I considered that, but it 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

Fails because a struct as struct and struct as namespace are not 
distinguishable.
