Haskell Weekly News: Issue 147 - January 24 , 2010
Welcome to issue 147 of HWN, a newsletter covering developments in the Haskell community.
This week on the HWN, we have a new blogger in town, Bartek, over at '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 announced a new version of the ForSyDe DSL. This version provides more freedom in the declaration of process functions, as well as compatibility with base 4.
parameterized-data library v0.1.4. Seyed Hosein Attarzadeh Niaki announced a new version of the parameterized-data library. The parameterized-data library provides fixed-sized vectors, this update is provide minor compatibility fixes.
Updates and a new member of the Monadic Regions family. Bas van Dijk announced several new updates and a new member of the Monadic Regions family.

Haskell XML Toolbox Version 8.5.0. Uwe Schmidt announced a new version of the Haskell XML Toolbox (HXT). The main change in this version is the separation of the XPath and XSLT modules.
Cardinality-0.1. Andrey Sisoyev announced the release of his package Cardinality, a package for transforming between container types safely.
afv-0.0.3. Tom Hawkins announced a new release of AFV, an infinite state model checker for simple, iterative C programs.
CfP: PPDP 2010. Temur Kutsia announced a call for papers for the PPDP 2010 conference in July
Mini-announce: A few package updates. Andrew Coppin announced several new releases and updates to AC-EasyRaster-GTK, AC-Vector, and other packages.

haskell-src-exts 1.7.0. Niklas Broberg announced a new version of haskell-src-exts, featuring many new changes to the API.
Existential Types (I guess). Ozgur Akgun asked about a problem he encountered when trying to use Existential types.
Is Haskell capable of matching C in string processing performance? John Millikin asked a question about Haskell Performance... Quick! Someone get Don Stewart!
Blog noiseHaskell news from the blogosphere. Blog posts from people new to the Haskell community are marked with >>>, be sure to welcome them!
++Bartek Paczesiowa++: 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.
