  there is.  READ-SEQUENCE and WRITE-SEQUENCE.  apply it to vectors of some
  reasonable machine size (8192 is frequently large enough to hold at least
  one complete disk block) having an element-type of either CHARACTER or
  (UNSIGNED-BYTE 8), and make the streams match that type.

  SIGTHTBABW: a signal sent from Unix to its programmers at random
  intervals to make them remember that There Has To Be A Better Way.
