Packages exposing functions that can stop program execution by exiting are hard to reuse. Program exits in functions other than main() or init() are not encouraged.

Bad practice

func nonMainFunc() {
    safelyExit := true // somehow arrive at this value

    if safelyExit {
        os.Exit(0)
    }
}

func main() {
    nonMainFunc()
}

Recommended

func nonMainFunc() bool {
    safelyExit := true // somehow arrive at this value
}

func main() {
    safelyExit := nonMainFunc()

    if safelyExit {
        os.Exit(0)
    }
}
