这个上面的问题，如何解决解决？
调用参数可以在类生成的时候 装饰一下，但是成员访问，复写了 __get__ 和 __set__ 方法好像没有效果

    attribute_acceses = []

    @wraps(f)

        start = time.time()
        ret = f(*args, **kwargs)
        Debugger.method_calls.append({
            'class': type(args[0]),
            'method': f.__name__,

            'kwargs': kwargs,
            'time': time.time()-start
        })
        return ret
    return new_func
