Go does have a way: use a pointer, as that code is doing. Or you could use a separate field to record whether the value is set. Or you declare a type that uses two bools, and use that. And no doubt there are other ways to do it. So there are several possible approaches. I'm guessing you want one that is more implicit, but as a general guideline Go tends to prefer explicit code.
