  Yes.  We have an important principle in Common Lisp: Write-read
  consistency.  That means that whenever an object is printed out and
  *print-readably* is true, reading it back in produces an object that
  consistent with the object printed out.  Achieving this is not always
  cheap, but it is a very, very important property of a language that
  defines the operations write and read for its objects through textual
  representation.  Inferior languages may not go the great lengths that
  are required to maintain write-read consistency, however.
