- : The instance on which to implement IEnumerable.
- createMoveNext: A factory that, given the container, returns a moveNext function. moveNext should return true if more elements remain; otherwise false.
- this: The enumerator. When a new value is generate it should be stored in this.current_.
- instance: The instance to enumerate.
