The code below doesn't work. Is it possible to make a pure 
opEquals in a class?

                pure bool opEquals(const A rhs) const
                {
                        return b == rhs.b;
                }

It doesn't work because `rhs` has the wrong type. It must be 
`Object`.

    override pure bool opEquals(const Object rhs) const
    {
        const A a = cast(A) rhs;
        return b == a.b;        
    }
