[Haskell] Announcing Haskell 2010

[David Leimbach]

First off congratulations everyone!

Second, Oh shit!  Graham Hutton's excellent Haskell introduction book is now
not valid Haskell 2010 due to N+K patterns?

I loaned that book to my boss and he's really enjoyed it.  I guess I'll have
to buy a revised copy.  Can we get an update to it? :-)

I realize N+K was considered dangerous
