Right, but that is something we can catch with "override".

The reason I like to have them there, besides having it immediately
visible, is the case

struct A {
	virtual void foo();
};

struct B : A {
	void foo();
};

struct C : B {
	void foo();
};

{
	B *b = new C;

	b->foo();
}

This calls C::foo(), until the signature of A::foo() changes, then it
starts calling B::foo().
