Should the traits/aspects even be overridable then? If they are it sounds like they need to be implemented the same as inheritance and this would basically just make them a different syntax for multiple inheritance. I don't think that's what Sven had it mind and if he did why not just do proper multiple inheritance using the existing syntax that interfaces uses?
