This struct should be specialized for third‐party types that need to declare the fact that they have a fallback enumerator value. Clients that specialize this struct must ensure that if HasFallbackEnumerator<TYPE>::value is true, then IsEnumeration<TYPE>::value is also true; otherwise, the behavior is undefined.
