Oh?  In what sense?

It seems to work fine for data types representing bounded enumerable
values with a proper mapping to/from Int (it's not bijective since
there's no proper mapping from Int -> Bool for example); the problem is
the fact that Double, etc. are made instances of Enum when this is not
the case for those data types.
