Can you have the decorator outside the class, calling a regular method
to do its main work?

def recon_if_needed(f):
    def inner(self, *a, **kw):
        if self.disconnected: self.connect()
        return f(self, *a, **kw)
    return inner
class SocketWorker:
    def send_packet(self, packet):
        assert not self.disconnected
