By default cabal uses ghc -O to build projects, so you won't see any difference if you comment it out of the cabal file. You will however if you explicitly turn off optimisations: ghc-options: -Onot I'd recommend using -O2 these days, particularly for a library like docon where performance matters. ghc-options: -O2 For best results. -- Don _______________________________________________ Glasgow-haskell-bugs mailing list Glasgow-haskell-bugs@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs
