(1+ fixnum) IS a fixnum in Franz. It is fairly important to our compiler
that it be. It could be important that sqrt returns a real for similar
reasons. You can record my vote as saying that IF sqrt returns complex
sometimes, then there should be another say, sqrt-real. If you want to
treat arithmetic as 2nd class, a tradition in Lisp, fine.
