public interface EnumWithStableIndex
Classes implementing this interface guarantee that for each instance of this class, there exists an mutually unique integer which is stable in time, and identifies always the same instance of this class. The index might be used for persistence, hence the index of a particular item cannot be changed. This is mostly usable for @{code enum}s.
