Main := () {
    Print("Hello, world!")
    Greetings := Make_greetings("Fall in love with programming!")
    @ index, value := Greetings.WithIndex()... {
        ? index == 0 { 
            Print(value, ", 世界!")
        } | {
            Print(value, ", world!")
        }
    }
}

Make_greetings := (input : Str -> output : List{Str}) {
    <- List_of(input, "你好", "Hola", "Bonjour",
                "Ciao", "こんにちは", "안녕하세요",
                "Cześć", "Olá", "Здравствуйте",
                "Chào bạn")
}
