Consequently, the circle viewed as a point still has Circle as a type description because the pointer in its .class com- ponent has not changed. draw is a selector function, i.e., it will take whatever argument is passed as self, proceed to the type description indicated by .class, and call the draw method stored there.

这个被看作是点的圆依旧是Circle类型的，因为其类型描述结构中的。class指针成员没有变化。draw是选择子函数，也就是说，它能接受任何以self参数传来的值，找到由。class指向的类型描述符，并且调用存储在那里的方法。
