I don't understand the motivation here. If you want to use Haddock with literate Haskell it has to look something like > -- | Foo > someCode = undefined I believe it does not matter to GHC whether we give it -- | Foo, no blank line someCode = undefined or -- | Foo, blank line someCode = undefined Haddock would see both as just someCode with a comment attached. I imagine you're suggesting that something like Literate comment > someCode = undefined is allowed but your justification using Haddock doesn't make sense in this case: ‘Literate comment’ will not be visible. Correct me if I'm wrong on anything here, I very rarely use the .lhs . -- Mateusz K. _______________________________________________ Glasgow-haskell-users mailing list Glasgow-haskell-users@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
