发现一个完全没用的 C++ 语言“特性”
可以使用
但是在子类中，你也必须使用
另外，在子类中你也不能使用
可以使用
= delete 来定义一个虚函数：
struct B { virtual void m() = delete; };
但是在子类中，你也必须使用
= delete 来定义对 m 的重写：
struct D : B {
void m() override; // ERROR
void m() override = delete; // OK
};
另外，在子类中你也不能使用
= delete 来重写一个在父类中没有被定义为 = delete 的虚函数：
struct B { virtual void m(); };
struct D : B {
void m() override = delete; // ERROR
};

我一直以来都认为 NSF 对 system research 弊大于利；但重点并非政府该不该为自然科学花钱（当然应该！），重点在于这笔钱有没有被可问责的方式分配。
最后推荐一本书，我看了受益匪浅 The Unaccountability Machine: Why Big Systems Make Terrible Decisions - and How The World Lost its Mind
