Haskell Weekly News
Issue 151 - February 28, 2010
   Welcome to issue 151 of HWN, a newsletter covering developments in the
   [1]Haskell community.

   A light HWN this week, some interesting discussion about view patterns
   and free monads. Also announced this week was [2]TryHaskell a
   work-in-progress online interactive haskell interpreter and tutorial.
   The author (based on his reddit post) has asked us not to post this to
   proggit yet, but I don't think he'll mind a plug here. So after you're
   done reading, give it a try! Until next week, haskellers, your Haskell
   Weekly News.


   wxHaskell for ghc-6.12.1. Daniel Fischer [3]announced a new release of

   concurrent-extra-0.2. Roel van Dijk [4]announced a new release of

   jhc-0.7.3. John Meacham [5]announced a new version of jhc, including
   many bug fixes.

   Try Haskell! An interactive tutorial in your browser. Benjamin L.
   Russell [6]told us about the TryHaskell Project, available at
   [7]TryHaskell.org. TryHaskell is an interactive, online Haskell
   interpreter and tutorial.

   MSFP: Call for Papers. Venanzio Capretta [8]announced a call for papers
   for the Third Workshop on Mathematically Structured Functional

   HLedger 0.8. Simon Michael [9]announced a new version of hledger last
   week, but it slipped through my radar. This release includes bug fixes,
   some refactoring, and High-Res Graphical Chart generation capability.


   View patterns. Andrew Coppin [10]asked about making view patterns

   What are 'free' Monads? Guenther Schmidt [11]asked what exactly it
   meant to be a 'free monad'

   Multiple Interpretations for a monad? Guenther Schmidt [12]asked about
   monads which can have multiple levels of meaning and interpretation.
