I must correct myself here. Even if for practical purposes traits look like a restricted multiple inheritance, in principle it is better to think of them as of an enhanced single inheritance. With traits there is always a single superclass: traits are just single inheritance with a nice syntax to include methods (like in Ruby) and a guarantee that methods will not be overridden silently (this one is missing in Ruby).
