Happstack is currently mtl based. I think I like transformers better, though I am saddened to see they do not have the classes like MonadReader, MonadWriter, etc.
http://hackage.haskell.org/packages/archive/monads-fd/0.0.0.1/doc/html/Contr...
Transformers is intended to be used with either "monads-fd" (to get
those instances using fundeps) or "monads-tf" (similar formulations with
type families.)
Monads-fd should be backwards-compatible w/ mtl.
