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.

extern(C++) class Base {
    ~this();
    abstract void foo();
}
