code: def call_no_reply(self, fn, *args, **kwargs):
          
          LOG.debug('%r.call_no_reply(): %r', self, CallSpec(fn, args, kwargs))
          self.context.send(self.make_msg(fn, *args, **kwargs))
docs: Like :meth:`call_async`, but do not wait for a return value, and inform
          the target context no reply is expected. If the call fails and
          pipelining is disabled, the exception will be logged to the target
          context's logging framework.
