I'm not entirely sure I follow you here. Is this what you mean?

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

void main() {
     foo();        // Either this does not work, (#1)
     nspace.foo(); // or this does not work.     (#2)
}

If so, is that really bad? I'd say the better choice is to make #2 work, as then 
#1 can be made to work with a simple alias:

alias foo = nspace.foo;

If I'm far off into the fields of ignorance now, care to show me the way to a 
better understanding?
