Re: [Haskell-beginners] Which IDE use a professional Haskeller?

There are a few features that I think are important for professional development: - debugging support - project management (should I really learn cabal packaging?) - underline sintactic errors - code navigation - autocompletion (based on scope) - testing integration

Optional valuable features - syntax highlight - section folds

I think EclipseFP gives you this. (I can't remember if it supports section folds, Haskell is sufficiently terse that I've never needed it :-)
