func finished[T](sc: Scanner[T]): bool
func prev[T](sc: Scanner[T]): T
func curr[T](sc: Scanner[T]): T

func peek(sc: Scanner[Rune]; n: int): Rune {...}{.raises: [], tags: [].}
func find(sc: Scanner[Rune]; r: Rune): int {...}{.raises: [], tags: [].}: return number of consumed chars. The scanner's position is not moved. -1 is returned when char is not found
