I have uploaded these to hackage. The packages are:
transformers: monad transformers, operations and liftings. This is all Haskell 98, and be used on its own, or as a base for packages defining monad classes.
monads-fd: monad classes using functional dependencies, with instances for the transformers in the transformers package. This is mostly backwards-compatible with mtl.
monads-tf: monad classes using type families, with instances for the transformers in the transformers package. This is mostly backwards-compatible with mtl-tf.
Great! (will all people associate 'transformers' with 'monad transformers'?)
