如果我创建如下的装饰器：

def my_decorator(some_fun):
    def wrapper():
        print("before some_function() is called.")
        some_fun()
        print("after some_function() is called.")
    return wrapper

@my_decorator
def just_some_function():
    print("Wheee!")

另一个装饰器可以定义为：

def my_decorator(some_fun):
    print("before some_function() is called.")
    some_fun()
    print("after some_function() is called.")

@my_decorator
def just_some_fun():
    print("some fun")

两个装饰器将工作相同。在装饰器中使用“包装器”功能有什么好处。我没有达到目的。
