The trouble mostly appears in this situation:
file1.d

file2.d
   extern(C++, NS) struct Y;

file3.d

   X x; // nope
   Y y; // nope
   NS.X x; // NS has multiple definitions...
   NS.Y y; // NS has multiple definitions...

    file1.NS.X x;
    file2.NS.Y y;

works.

Why not produce something similar to an overload set for C++ 
namespace ? An error needs to be issued only if X or Y is 
duplicated, otherwise, this is fine.
