    Subject: boole

    You guys are kidding, right?  BOOLE is a hideous function that was only
    kept around so that rasterop harware and suchlike could be used in a
    direct way from within Lisp.  What possible purpose could served by
    extending it to N values?  It is not a stated goal of Common Lisp to
    provide an interpretation for all possible extensions to all possible

BOOLE isn't being extended to N arguments (NOT values!).  It has always
taken N arguments (2 or more).  It's well-defined what this means.  I notice
there seems to have been a decision to limit it to 3 arguments in the
Common Lisp subset, which is acceptable if gratuitous.
