docs: // QueueSubscribeSyncWithChan will express interest in the given subject.
  // All subscribers with the same queue name will form the queue group
  // and only one member of the group will be selected to receive any given message,
  // which will be placed on the channel.
  // You should not close the channel until sub.Unsubscribe() has been called.
  // Note: This is the same than ChanQueueSubscribe.
