单通道执行常规死锁

一种可能的解决方案是避免使用select语句，并为接收者（或发送者，或两者）使用单独的goroutine。例：

package main    import "sync"func worker(res chan bool, wg *sync.WaitGroup) {    res <- true    wg.Done()}func receiver(res chan bool, wg *sync.WaitGroup) {    for range res {    }    wg.Done()}func main() {    var wg, wg2 sync.WaitGroup    wg.Add(1)    wg2.Add(10)    found := make(chan bool)    go receiver(found, &wg)    for i := 0; i < 10; i++ {        go worker(found, &wg2)    }    wg2.Wait()    close(found)    wg.Done()}
