我理解静Subtyping polymorphism 即动态多态性是指的虚函数，即用override virtual function的方法，名字和参数都相同，但继承类不同。运行时根据指针类型决定调用函数。override应该翻译成重写或者覆盖

而Parametric polymorphism所谓静态多态性则指的generic或者template，这是在编译时根据参数类型而绑定的。

而operator overload则是函数名相同，参数不同，这跟多态性一点关系没有，只是方便人类阅读记忆，对程序没区别，编译时会自动改名为不同名字的函数。

可悲的是这08年的错误文章竟然在google搜索“多态性”时名列第二，不知道有多少人都误解了
