One of the things those of us on your side *begged* for (and
apparently also didn't get) was that the versions with correct
behavior not have second-class names. That we didn't get them means
we'll have to provide them ourselves, but it's easy. Since we're
having to fix code anyway, just use a file containing something like:
(def add +')
(def sub -')
(def mul *')
(def add1 inc')
(def sub1 dec')
when you need it.
