    Es handelt sich also hier um eine Generatorfunktion, die die „generierende“ Arbeit intern auf etwas anderes überträgt.

    Auf diese Weise können wir das Ganze in einen `with`-Block einfügen und so sicherstellen, dass das dateiartige Objekt nach Abschluss geschlossen wird.

/// tip | "Tipp"

// returns true if the node changed state from online to offline
func (c *Client) MarkOffline(err error) bool {
	c.Lock()
	c.lastErr = err
	c.lastErrTime = time.Now()
	atomic.StoreInt64(&c.lastConn, time.Now().UnixNano())
	c.Unlock()

	return c.runHealthCheck()

    Então, é uma função geradora que transfere o trabalho de "geração" para alguma outra coisa interna.

    Fazendo dessa forma, podemos colocá-la em um bloco `with`, e assim garantir que o objeto semelhante a um arquivo é fechado quando a função termina.

      Iterator<V> i = values.iterator(); // Must be in synchronized block
      while (i.hasNext()) {
