Also, toEnum and fromEnum would make more sense mapping from and to Integer.
Why do we need toEnum and fromEnum at all? As far as I know, they are merely there to help people implement things like enumFrom.
They are often useful for writing serialisation routines, and they see occasional use for other kinds of safe type coercion as well (toEnum . fromEnum) Regards, Malcolm
