func main() {

	// SetDefaultExpire sets default expiration for value in Map.

	m.SetDefaultExpire(time.Second / 2)

	// Store sets the value for a key with default expiration.

	m.Store("key1", "foo")

	// Load returns the value in expiration stored in the map for a key,

	// or nil if no value is present.

	v, ok := m.Load("key1")

	if !ok {

		return

	}

	fmt.Println("key1:", v)

	// Store with expire sets the value for a key with expiration.

	m.Store("key2", "bar", expiremap.Expire(time.Second / 2))

	v, ok = m.Load("key2")

	if !ok {

		return

	}

	fmt.Println("key2:", v)

	// Wait for expiration

	time.Sleep(time.Second)

	_, ok = m.Load("key1")

	if !ok {

		fmt.Println("key1 expired")

	}

	_, ok = m.Load("key2")

	if !ok {
