The "Cc"ed individual above uncovered an interesting difference between
interpreted and compiled CommonLisp on a Sun workstation that generated
a splurge of conversation here. In particular:
(null (null '(a b c))
returns T when interpreted, but returns (a b c) when compiled.
My question for you: Does (not (null '(a b c)) do the same thing in the
same implementation, or does it always return T?
