My Haskell experiments have reached a size in which debugging tools would be more than welcome, so I looked around, and was very disappointed. I tried Hood, which is a pain to use (lots of editing of the code required), I looked at Buddha but didn't want to downgrade to GHC 5 for trying it (nor is my code Haskell 98, because of multi-parameter classes), and all that seems left to try is Hat, whose Web site I can't reach at the moment.
So what are you Haskell programmers using for debugging in real life?
I have found that an approach based on unit testing (using HUnit) eliminates most requirements for a debugger. When I have problems, I resort to ad-hoc techniques, sometimes exposing (exporting) the inner workings of a module for testing/exploration purposes.
