Hi, Why GHC doesn't tell me such things like hpaste? (example here: http://hpaste.org/82917) 27:12: Error: Use replicateM Found: sequence $ replicate gridSize getLine Why not: Control.Monad.replicateM gridSize getLine 50:14: Warning: Use list comprehension Found: if y > 0 then [(UP, (x, y - 1))] else [] Why not: [(UP, (x, y - 1)) | y > 0] 81:1: Error: Eta reduce Found: sortByPathCost p ps = sortBy compareHeuristic ps Why not: sortByPathCost p = sortBy compareHeuristic Can I enable this kind of verbosity in GHC somehow?
