Well, I mostly do client side templating, so most of my functions end up being (ToJSON a) => ScottyT a, which simplifies matters. Problems: not thrilled with the error handling, I prefer using Either rather than the out of band exception stuff Scotty seems to use. However, it's Haskell, so I can almost always write a small function to do what I want. For example, param is :: (Read a) => String -> ScottyT a, and throws an exception if the param does not exist. It is trivial for me to write a function paramM :: (Read a) => String -> ScottyT (Maybe a), so the original problem is not significant. Never used mflow, looks interesting, but I wouldn't use it.
