If you know how your C++ compiler mangles functions inside 
namespaces, you should be able to hack something together using 
pragma mangle. I'm not sure how nice it can be, ideally a UDA 
(user defined attribute) should be enough, but I've never used 
them myself so I don't know if this is possible:

@Cpp("namespace") void foo(int x);

or even:

@Cpp("namespace")
{
   void foo();
   void bar();
}

where @Cpp applies extern(C++) and pragma(mangle, 
"correctlymangledname"). Anyone knows if this can be done?
