不能以一个参数进行调用的构造函数不应当加上explicit. 接受一个std::initializer_list作为参数的构造函数也应当省略explicit, 以便支持拷贝初始化 (例如MyType m = {1, 2};). 3.3. 可拷贝类型和可移动类型 总述 如果你的类型需要, 就让它们支持拷贝 / 移动. 否则, 就把隐式产生的拷贝和移动函数禁用. 定义...

它们不是同一回事---x 是int, y 则是std::initializer_list<int>. 其它一般不可见的代理类型(acgtyrant注:normally-invisible proxy types, 它涉及到 C++ 鲜为人知的坑:Why is vector\ not a STL container?)也有大同小异的陷阱。 如果在接口里用 auto,比如声明头文件里的一个常量,那么只要仅仅因为程序员...
