Comment #2 on issue 373 by wil...@willem.vanlint.name: Hlintify XMonad & XMonadContrib http://code.google.com/p/xmonad/issues/detail?id=373 I've patched a few of the Hlint flags in xmonad core. It is indeed a nice beginner project, I learned a lot. I left one of the eta reduction warnings in there due to readability and I didn't alter the naming of the atoms to camelCase due to their origin. When applying another eta reduction, I noticed the redundant use was a solution for the monomorphism restriction. This was changed by using scoped type variables also due to the possibility that generalisation isn't done in nested expressions (http://hackage.haskell.org/trac/ghc/blog/LetGeneralisationInGhc7). Any comments on my patch are welcome. Attachments: hlint-fixes.dpatch 14.7 KB
