	Except that the first option could be extended to allow overriding
several methods from the same interface at once:

class LotterySimulation : Lottery, Figure {
     override(Lottery) {
         void draw();
         void foo();
     }
     override(Figure) {
         void draw();
         void foo();
     }
}
