  Let's see is the person requesting this can describe it well enough
  to be implementable or even desirable in Common Lisp.  I'm not too
  interested in what it would mean in another language, but this is
  probably because I occasionally use English expressions in Norwegian
  and vice versa and thus know just how incredibly embarrassing it can
  be to forget which language one is using.

  If this is not what you expected, please alter your expectations.
