That won't work well, since super does *not* go to self.superclass -- actually, that's the very reason it's solved compile-time :)

I believe it would be solveable; nevertheless, myself, I am yet to see a reasonable code which does [super something] in a trait code. So, in my implementation, I simply documented super as invalid with "undefined results" :)
