如何使用内建函数`recover`终止`panic`过程（参考[章节13.3](https://github.com/Unknwon/the-way-to-go_ZH_CN/blob/master/eBook/13.3.md)）：
~~~
func protect(g func()) {
defer func() {
log.Println("done")
// Println executes normally even if there is a panic
if x := recover(); x != nil {
log.Printf("run time panic: %v", x)
}
}()
log.Println("start")
g()
}
~~~
