--- Comment #1 from yebblies <yebblies@gmail.com> ---

The requested example of how to create classes usable through extern(C++) interfaces - pretty much how you'd expect.

import std.stdio;

extern(C++)
interface I
{
    void fun();
}

extern(C++)
class C : I
{
    void fun() { writeln("This works..."); }
}

class D : I
{
extern(C++):
    void fun() { writeln("And so does this!"); }
}

void main()
{
    I i = new C();
    i.fun();
    i = new D();
    i.fun();
}

Thanks.

An updated unit test:

version(unittest)
{
   extern(C++) interface X
   {
   }

   extern(C++) class C : X
   {
   }
}

unittest
{
   X x = new C;
   string expected = format("%X", cast(void *)x);
   formatTest(x, expected); // fails, x is printed as 'null'
}

@yebblies While fiddling around, I found an issue with extern(C++) classes (not
related to this). See issue #12636
