Feedback before mid-August 2006 would be particularly valuable. The Haskell-prime committee has started work on defining the next minor revision of the language specification. "Haskell is the programming tool of choice for discriminating hackers" for the second year running! The teams winning first and third place in the ICFP 2005 programming contest both used Haskell.
