  (1) Multiple inheritance could well take a constrained form that does
  not have the many gotchas you see even in CLOS.  Consider a piece
  of Java that looks like this:

     public class InputOutputWindow
	 extends Window
	 implements Input using InputMixin
	 implements Output using OutputMixin {
       ....
     }

Before you get into details, note that this is a starting point. 
Matthew have done some additional theoretical and practical work 
on this topic.
