I think the latest specification does not allow declaring index and values.

About values: "It's a compile-time error if the enum declaration contains a static or instance member declaration with the name values, or if the superclass or any superinterface of the enum declaration has an interface member named values. A values static constant member will be provided for the class, this restriction ensures that there is no conflict with that declaration."

About index: "It's a compile-time error if a class, mixin or enum declaration has Enum as a superinterface, and it declares a non-abstract instance member named index. That member would override the index getter inherited from Enum, and we currently do not allow that."
