[Haskell-cafe] Can't get my head round monad transformers

[Colin Adams]

I'm trying to add a state monad onto the IO monad for use in a
happstack application. I thought this should involve using StateT and
Happstack.Server.SimpleHTTP.simpleHTTP', but I can't figure out how to
plumb it all together. Any tips will be welcome.
