Registering Zyre socket fails with "TypeError: unhashable type: 'Zsock'"

Unable to use Zyre with Poller. Python version 3.12, zyre 2.0.0, zeromq 4.3.5

    poller.register(zyre.socket(), zmq.POLLIN)

    print("Success")

Interesting. I guess you are using the generated ctypes binding? You must know that the zyre call returns a a czmq zsock instance. You should call zsock_resolve (C) to get to the zmq socket. In python I guess that would be the instance resolve() method. But I'm doubtful it will work. But please confirm what bindings you are using.
