}

export function isRef<T extends object>(k: T): boolean {
  return internal_refSet.has(k)
}

export function deepCloneWithRef<State extends object>(initialState: State): State {
  const cloned: State = createObjectFromPrototype(initialState)

  for (const key in initialState) {
    const value = initialState[key as keyof State]
