Solve the following python programming problem given the following code:
def dict_extractor(node) : 
    def wrapExpressionBuiltinDictCreation(positional_args, dict_star_arg, source_ref) : 
        if (len (positional_args) > 1) : 
            result = makeRaiseExceptionReplacementExpressionFromInstance (expression = node, exception = TypeError (('dict expected at most 1 arguments, got %d' % len (positional_args)))) 
            result = wrapExpressionWithSideEffects (side_effects = positional_args, old_node = node, new_node = result) 
            if dict_star_arg : 
                result = wrapExpressionWithSideEffects (side_effects = dict_star_arg, old_node = node, new_node = result) 
return result 
return ExpressionBuiltinDict (pos_arg = (positional_args [0] if positional_args else None), pairs = dict_star_arg, source_ref = source_ref) 
return BuiltinOptimization.extractBuiltinArgs (node = node, builtin_class = <MASK>, builtin_spec = BuiltinOptimization.builtin_dict_spec) 
    
    Given the code above, what is a proper replacement for <MASK>? Choose among: node
assistant
#Here is a proper replacement for <MASK>.
