This is a simpler way of preventing inheritance:

There's another problem with Final that lets you derive from it in a
class with user-defined constructors, if you know how. Our wiki where
I work offers a chocolate bar to anyone who points it out but noone's
claimed it from me yet :)
class WillCompile : public Final, virtual Finaliser {
public:
	WillCompile() {}
};

Will you mail the chocolate bar to me then?
