Hmm.  I didn't notice this the first time through, but this doesn't
read so well.  (- 5) looks like -5.

I suppose

(++ 5)    =>    6

might be better, although of course it isn't like the C ++ because it
just returns the incremented value, rather than assigning.

There's also

(inc 5)

Or of course going back to (+ 5 1) if all of these choices seem
problematic.
