Having spoken to some people in #scheme (freenode), I've heard some
good reasons for using #!void as a default, so I apologise for being
overly rash with my comment! The IF implementation will need to be
tweaked for CL, as a missing else branch is not undefined behavior in
CL (as it is in Scheme), it must default to NIL.

Charles.
