Oh yes, so it is. Did this proposal get discussed on any mailing list?

I'd just like to float an idea that's related to the Class Alias

We all know that Functor should have been a superclass of Monad, and
indeed we now know that Applicative should be too. Making such a change
would break lots of things however so the chang

One day we hope Cabal will support yhc. It currently supports ghc, hugs

The main thing holding it back is dependency chasing in Cabal or the

So now that GHC 6.8.1 is out you'll want to test your package with it.
We'd especially like maintainers of packages that are distributed on
