其实对于类的偏特化，感觉拿std::remove_reference来举例子更好一些

template<typename _Tp>
struct remove_reference
{ typedef _Tp   type; };

template<typename _Tp>
struct remove_reference<_Tp&>
{ typedef _Tp   type; };

template<typename _Tp>
struct remove_reference<_Tp&&>
{ typedef _Tp   type; };

不仅仅是能够偏特化到具体的类型，甚至还可以偏特化到左值右值
