   'The Power of Types Compels You', wrote an excellent article which is
   highlighted in the blogs section. Many new packages this week as well,
   and some interesting discussions about performance and existential
   types. So, Haskellers, till next week, your Haskell Weekly News!


   ForSyDe DSL v3.1. Seyed Hosein Attarzadeh Niaki [2]announced a new

   declaration of process functions, as well as compatibility with base 4.

   version of his package bindings-DSL.

   Haskell XML Toolbox Version 8.5.0. Uwe Schmidt [6]announced a new

   Millikin [16]asked a question about Haskell Performance... Quick!
   Someone get Don Stewart!

Blog noise

   [17]Haskell news from the [18]blogosphere. Blog posts from people new
   to the Haskell community are marked with >>>, be sure to welcome them!
     * ++Bartek Paczesiowa++: [19]Pure, extensible exceptions and
       self-returning functions. Bartek, over at 'The Power of Types
       Compels You', wrote a fantastic introduction to his forthcoming
       exceptions package. It's funny, and a great read about using type
       families (particularly, equality constraints) to create a pure
       exception handling mechanic. Definitely worth a visit.
