'()

[Norman Adams <Adams at YALE>]

About '():
  The T Project style sheet says
  (a) False and the null list are not assumed to be the same object
  (b) The variable NIL has false as its value; we don't depend on its
      having an external representation
  (c) Don't assume the empty list evaluates to itself
  
  Consequences:
  (a) Notate the empty list as '() in programs
  (b) Notate false as NIL

The T style sheet is highly tuned dogma that we encourage you
to use,  though we plan no inquisition for the infidels.

RAK found a bug in WALK that we have fixed -- "the WALK that
really works" was his patch.
