proposal: - symbol

[switchupcb]

Add an assignment symbol (-) that returns a named variable if it's not it's zero value. This is definitely NOT an error proposal. If you think it is, I know a doctor who can check your eyes for you. For free! Call me, 😉.

The zero value of an error (which is a value) is nil.

func bezo(baller, dollers string) error {
    bucko, - := strconv.Atoi(baller)
    bucks, _ := strconv.Atoi(dollers)
    fmt.Println("$:", bucko + bucks)

    return nil
}

I'm sorry, this is clearly not going to happen. The - and _ symbols look too similar to have such radically different effects. And nothing in Go permits change in flow of control based on an operator. I could run the proposal through the whole process, but frankly that would just be wasting people's time. I'm going to close out this issue. Sorry.

I encourage you to discuss language issues in a forum like golang-nuts rather than by filing proposal issues. Thanks.
