Annotate individual switches

[Egon Elbre]

Sometimes it makes more sense to annotate every exhaustive switch separately.

//enumcheck:silent
type Option string

var (
	Alpha = Option("alpha")
	Beta  = Option("beta")
)

func NoErrorHere() {
	var day Option
	switch day {
	case Beta:
		fmt.Println("beta")
	}
}

func EnablePerSwitch() {
	var day Option
	switch day { //enumcheck:exhaustive
	case Beta:
		fmt.Println("beta")
	}
}
