Seems there's some trouble with your mail server, I keep getting 'delivery failure'. Hopefully mails through the list will get through. Anyway, I've now merged my repo with the changes to haskell-src in CVS. There were no merge conflicts.
I'd also like to parameterize the parser over the Extensions type currently in Distribution.Extension (maybe it should move to Language.Haskell.Extension) so that users could selectively enable extensions.
I agree that the parser (and the lexer too) should be parametrized over extensions. The Extensions type in Distribution.Extension looks a bit messy, but I guess that's a different issue entirely, I suppose once that's stable we'll have no problems using it. I've started adding some infrastructure to my lib for doing this parametrization, it seems to be fairly straight-forward (but tedious). I'll keep working on it. There are a few non-conservative changes introduced in haskell-src-exts, so I guess it's best to wait until all the extension parametrization is there before adding my stuff to the official cvs. /Niklas
