You could strip comments with something like this. The results might be slightly better, depending on how well sim works. Haskell-src-exts is improving, but it still fails on a couple modules in contrib.
#!/usr/bin/env runghc
import System.Environment import Language.Haskell.Exts import Control.Monad
main = mapM_ (putStrLn . prettyPrint . fromParseResult <=< parseFile) =<< getArgs
That's useful, but I think it's not as good as changing the module headers. As you say, that will choke on some modules; it's an extra step; and by removing comments entirely, one can no longer investigate any duplication in *comments* as well as code (I'm sure copy-pasta of comments exists, even if only in the module headers.) And I don't entirely understand the reticence to use multi-line comments. Weren't they intended for exactly these sorts of situations, massive comment blocks spanning entire pages? How exactly are a couple hundred prefixed '--'s superior to a {- -}? -- gwern
