你好，最近在學golang，有幸學習您的文章，關於你的deadlock例子，我認為是因為channel必須跟gorutine同時存在，所以邏輯判斷上應該是有確定要使用gorutine時，才建立channel，
func main() {
totalResult := 0
needRoutine := false
if needRoutine == true {
c := make(chan int)
go func() {
result := 1
c <- result
}()

totalResult = <-c*3 + 5
} else {
//do nothing
}

fmt.Printf("result is %d", totalResult)
}
不過跟你的解法其實差不多就是了 :)

大錯特錯
If the channel is unbuffered, the sender blocks until the receiver has received the value.
