Re: [Haskell-cafe] IDE

I've installed haskell-mode and some others from the package manager. Yet I have no auto-completion, no go-to-definition, no overview, no function lookup/search. I use Eclipse for Java, and it works out of the box. The lack of an easy-to-setup IDE is something I really miss in "Haskell environment". How much time would it take to setup emacs as an IDE for Haskell? Considering I'm pretty newby as emacs.
