Re: 'final' function implementations in interface definition

[grauzone]

What about this?

interface A {
  void foo();
  final int fun() { return 1; }
}

interface B {
  void bar();
  final int fun() { return 2; }
}

class C : B, A {
}

(new C).fun();

What does that do?

Simple: overriding final methods is illegal.
