I have to say I like Robert Clipsham's idea best:

extern(C++) module nspace {
     int foo(); // Is this also extern(C++)? I think it should be.
}

extern(C++) module nspace {
     module innernspace {
         int bar(); // Also extern(C++), if we follow the example above.
     }
}

I haven't the foggiest idea how C++ modules are supposed to work, so there might 
be clashes with those somehow?
