Re: [Haskell-cafe] Either instance of Monad?

      I have the same problem with instances of Functor.
For instance when I import Control.Applicative, to get the instance
"Functor ((->) a)" I also have to import Control.Monad.Instances.

The latest, I think :
GHC 7.0.1,
mtl-2.0.1.0,
base-4.3.0.0
Hmm, that's exactly what I have. Weirder and weirder.
For the moment, I'm out of ideas.
