class_docstr: The ZMQ socket object
  
  To create a Socket, first create a Context::
  
      ctx = zmq.Context.instance()
  
  then call ``ctx.socket(socket_type)``::
  
      s = ctx.socket(zmq.ROUTER)

docstr: Receive a Python object as a message using json to serialize.
  
  Keyword arguments are passed on to json.loads
  
  Parameters
  ----------
  flags : int
      Any valid flags for :func:`Socket.recv`.
  
  Returns
  -------
  obj : Python object
      The Python object that arrives as a message.
  
  Raises
  ------
  ZMQError
      for any of the reasons :func:`~Socket.recv` might fail
