Solve the following python programming problem given the following code:
def Open(self) : 
    if (not self._open_result) : 
        def open_impl() : 
            if (self._num_failures [0] > 0) : 
                self._num_failures [0] -= 1 
                self._state = ChannelState.Closed 
                raise Exception ('Error opening socket') 
gevent.sleep (self._open_delay) 
            self._state = ChannelState.Open 
self._open_result = AsyncResult () 
        self._open_result.SafeLink (open_impl) 
return open_impl._open_result 

    
    

    Fix the buggy line: return open_impl._open_result

#Here is Python code to fix the buggy line: return open_impl.

return self._open_result
