It doesn't provide instances of Num for anything which is already an instance of the other classes. And in Haskell 98 they must be defined separately for each type, instance (...) => Num a doesn't work.
It works in extended Haskell however, so I suspect it lays to rest the question of needing some other language extension. -- Ashley Yakeley, Seattle WA
