Hi,

I'm trying to implement unicode support for nhc98, but I'm confused by th=
is code:

---------------

module Prelude(Enum(..)) where

instance Enum Char where

    enumFrom n        =3D enumFromTo n (toEnum 255)
    enumFromThen n n' =3D enumFromThenTo n n' (toEnum 255)

    toEnum   c =3D toEnum c	-- MAGIC
    fromEnum c =3D fromEnum c	-- MAGIC

---------------

What does this "MAGIC" mean? Do the right hand sides use the prelude func=
tions of the compiler
that nhc is built with, or the internal representation of chars is define=
d in other place?

Regards,

Antonio Regidor Garc=EDa
