Solve the following python programming problem given the following code:
def __call__(self, fn) : 
    if hasattr (fn, '_sa_exclusion_extend') : 
        fn._sa_exclusion_extend (self) 
        return fn 
def extend(other) : 
        self.skips.update (other.skips) 
        self.fails.update (other.fails) 
@ decorator 
    def decorate(fn, * args, **kw) : 
        return self._do (config._current, fn, * args, ** kw) 
decorated = decorate (fn) 
    decorated._sa_exclusion_extend = fn 
    return decorated 

    
    

    Fix the buggy line: decorated._sa_exclusion_extend = fn

#Here is Python program to fix the buggy line: decorated.
