Note #14 argument reusing in fmt.Printf

Бывает необходимость напечатать несколько раз одно и тоже значение или значение и тип:

fmt.Printf("Num: %d %d\n", 2, 2)
// or
fmt.Printf("Num: %d %T\n", 2, 2)

Это легко переписать, используя индексы аргументов:

fmt.Printf("Num: %d\n", 42)
fmt.Printf("Num: %d %[1]d %[1]d %[2]d %[2]d", 2, 3)
}
