Solve the following python programming problem given the following code:
def next_extractor(node) : 
    def selectNextBuiltinClass(iterator, default, source_ref) : 
        if (default is None) : 
            return ExpressionBuiltinNext1 (value = iterator, source_ref = source_ref) 
else : 
            return ExpressionBuiltinNext2 (iterator = iterator, default = default, source_ref = source_ref) 
return BuiltinOptimization.extractBuiltinArgs (node = node, builtin_class = node, builtin_spec = BuiltinOptimization.builtin_iter_spec) 

    
    

    Fix the buggy line: return BuiltinOptimization.extractBuiltinArgs (node = node, builtin_class = node, builtin_spec = BuiltinOptimization.builtin_iter_spec)
assistant
#Here is Python program to fix the buggy line: return BuiltinOptimization.

return BuiltinOptimization.extractBuiltinArgs (node = node, builtin_class = def selectNextBuiltinClass(, builtin_spec = BuiltinOptimization.builtin_iter_spec)
