如何从Go渠道获取（并忽略）值

I have the following code in a select statement. finish is of type bool. Actually, I don't even care of the value as long as I just receive anything. However, Go gives me an unused variable error. How can I get around it?

case finish := <- termSig:

My current workaround is to Println(finish).

I had tried:-

case _ := <- termSig:

but that doesn't work either.

Just omit the variable and the :=:

case <-termSig:

As is shown in the Go Tour when select is introduced, you can have a case that doesn't initialize a new variable.

func fibonacci(c, quit chan int) {
    x, y := 0, 1
    for {
        select {
        case c <- x:
            x, y = y, x+y
        case <-quit:  // looks like exactly your use case
            fmt.Println("quit")
            return
        }
    }
}
