Welcome to issue 88 of HWN, a newsletter covering developments in the Haskell community.

An extra-short HWN this week, so you get an extra ten minutes to do something else during the time you would have normally spent reading the HWN! HWN-editor-approved activities for your ten minutes include eating cookies, playing Fantastic Contraption, and writing a type checker in the type system while eating cookies.

Announcements

Arch Haskell News: Oct 4 2008. Don Stewart sent out the newest Arch Haskell news --- now with 609 Haskell packages!

Announcing OneTuple-0.1.0. John Dorsey announced the release of the ground-breaking OneTuple library, which adds the long neglected one-tuple to Haskell. It also turns out that the denizens of Haskell-cafe are completely unable to refrain from turning jokes into long-winded technical discussions about strictness and lifted types.

Haskell protocol-buffers version 0.3.1. Chris Kuklewicz announced the release of protocol-buffers 0.3.1, with some functionality also split off into protocol-buffers-descriptor and hprotoc. The 'hprotoc' compiler for proto files to Haskell source code now takes a "-u" command-line option. When given, this turns on code generation to support loading, storing, and saving unknown fields.

Discussion

Stacking monads. Andrew Coppin began a long discussion on monads, monad transformers, Applicative, MonadPlus, and related topics.

planning for ghc-6.10.1 and hackage. Duncan Coutts began a discussion on how to make the transition to GHC 6.10 as painless as possible, especially as it relates to the new base-4 package and Cabal.

Proposal #2629: Data.List: Replace nub; add nubOrd, nubInt, nubWith. Bart Massey proposed refactoring nub into a 'nubWith' function which can be specialized to efficient versions for Int and Ord.
