I am really happy with HLint. Being relatively new to haskell world, I tend to be slow in finding ready-made solutions, or using folds fot recursive tasks. HLint 1.0 discovers `on` for me, and only for that I will be infinitely grateful. Now, if HLint 1.2 helps me with the map/fold understanding, I will be 'continuous infinitely' grateful (although real numbers are not representable!)
