# C++ 工具类

### defer
go 语言的defer很好用，所以想让c++也可以支持这样的功能  
defer 使用例子：  
```
int main() {
    defer (std::cout<<"defer 1"<<std::endl);
    std::cout<<"pos 1"<<std::endl;
    {
        defer (std::cout<<"defer 2"<<std::endl);
        defer (std::cout<<"defer 3"<<std::endl);
        std::cout<<"pos 2"<<std::endl;
    }
    std::cout<<"pos 3"<<std::endl;
    return 0;
}
/* 输出
pos 1
pos 2
defer 3
defer 2
pos 3
defer 1
*/
```
