Wrapping C++ class with virtual destructor

[Gregor Mückl]

Hi!

How do I wrap an existing C++ class with a virtual destructor in 
D? Take, for example, this C++ class:

class Base {
public:
     virtual ~Base();

     virtual void foo() = 0;
}

What does the equivalent extern(C++) declaration in D look like? 
I don't care about calling the destructor. My only concern is 
matching the vtable. Changing the C++ code is not an option in my 
case.
