  40    Caveat: It modifies the original string.
  41    Caveat: These functions cannot be used on constant strings.
  42    Caveat: The identity of the delimiting character is lost.
  43    Caveat: It doesn't work with multibyte strings unless all of the delimiter
  44            characters are ASCII characters < 0x30.
