const loopState: [State, Effect] = loop(
  { first: true, second: false },
  Effects.constant({ type: "SECOND" })
);

// ok
const model1: State = L.getModel(loopState);

// ok
const model2: State = L.getModel(state);

// ok
const effect1: Effect = L.getEffect(loopState);

// ok
const effect2: null = L.getEffect(state);

// $ExpectError
const effect3: Effect = L.getEffect(state);

// ok
L.isLoop(loopState);

// ok
L.isLoop(state);

const state: State = { first: true, second: false };
