「让我们一起 Golang」让协程自己 kill 自己

package main
import (  "fmt"  "runtime"  "time")
func task051()  {  defer fmt.Println("拿来吧你")
  fmt.Println("曲项向天歌")  fmt.Println("白毛浮绿水")  //杀死当前所在协程  // Goexit terminates the goroutine that calls it. No other goroutine is affected.  // Goexit runs all deferred calls before terminating the goroutine. Because Goexit  // is not a panic, any recover calls in those deferred functions will return nil.  //  // Calling Goexit from the main goroutine terminates that goroutine  // without func main returning. Since func main has not returned,  // the program continues execution of other goroutines.  // If all other goroutines exit, the program crashes.  runtime.Goexit()
  fmt.Println("红掌拨清波")}
func main() {  go func() {    fmt.Println("鹅鹅鹅")    task051()    fmt.Println("——骆宾王")  }()  // Sleep pauses the current goroutine for at least the duration d.  // A negative or zero duration causes Sleep to return immediately.  time.Sleep(time.Second)}
