It's pretty subtle, but the Haddock there does list an instance of MonadReader r ((->) r).

Yup, I see that one. What I meant was that in the Mondad package it says that ((->) r) is an instance of Monad, but I can't find way to get from there to Reader.

In newer GHC's the instance is also found in Control.Monad.Instances. In my opinion, it belongs in the Prelude. :)

Hmm. Yeah, it seems like there aren't many monad instances imported into prelude. Just [], Maybe and IO. I'll have to keep that in mind. Thanks for your help everybody. -- Lou.
