• like this

func main() {
	for i := 0; i < 100; i++ {
		func(i int) {
			gopool.Go(func() {
				fmt.Printf("%d\t", i)
			})
		}(i)
	}
        time.Sleep(5 * time.Second)
}

• but not like this

func main() {
	for i := 0; i < 20; i++ {
		gopool.Go(func() {
			fmt.Printf("%d\t", i)
		})
	}
	time.Sleep(5 * time.Second)
}
