It depends on what you want. But you can always use composition instead of inheritance for B. I have beenĀ  using things like alias this, mixin and ufcs to achive multiple iheritence and it works ok for me.

Since D does not support multiple inheritance, is there any way
to effectively achieve this?


class A;
class B;

class C : A, interface!B;

Then it is as if I have done


class A;
interface iB;
class B : iB;

class C : A, iB;

But I can then do

C c = new B;

(but since I can't make B inherit iB, this is impossible)
