Solve the following python programming problem given the following code:
def iter_extractor(node) : 
    @ calledWithBuiltinArgumentNamesDecorator 
    def wrapIterCreation(callable_arg, sentinel, source_ref) : 
        if (sentinel is None) : 
            return ExpressionBuiltinIter1 (value = callable_arg, source_ref = source_ref) 
else : 
            return ExpressionBuiltinIter2 (callable_arg = callable_arg, sentinel = sentinel, 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)

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

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