See http://rosettacode.org/wiki/Inheritance/Multiple#D
I feel that the entry is incomplete. I am a supported of full-fledged MI, à la Common Lisp or C++, and the argument that interfaces solve most problems that MI solves, for less of a hassle, leaves me completely cold, even cynical.
However, D is the first language that I have encountered that offers a real, manageable alternative to MI, as described in Andrei's book.
So I think it would be good if someone - Ali? - could expand that entry a bit. I could do it but I am still a rookie in D and I prefer it to be done by someone who is more seasoned than me.
