That's what interface inheritance means; if you fulfill the contract of the more derived type then you are required to also fulfill the contract of the less derived type.
接口继承就是这样的；如果你要满足派生程度较高的类型的契约的话，你就必须要满足派生程度较低的类型。
It also defines a Struct class for defining arbitrary data aggregations, and the special class any which can be used to represent any built-in or derived type and thus is the basis of dynamic typing.
它还定义了一个struct类，用来定义任意的数据聚合，此外，还定义了特殊的类any，它可以用来表示任何内置或导出类型，因而它也就成了动态类型化(dynamic typing)的基础。
