Haskell Weekly News
Issue 84 - September 06, 2008

   Welcome to issue 84 of HWN, a newsletter covering developments in the
   [1]Haskell community.

   This is the "This issue is not late since the HWN will henceforth be
   published on Saturday now that I have real work to do" edition.
   Featured this week: darcs hacking sprint plans solidify, xmonad 0.8
   released, typed sprintf and sscanf, and tons of discussion about
   everything from functional references to splitting up the base library
   to the future direction of Haskell.


   unicode-properties, unicode-names Ashley Yakeley
   [2]announced the release of the [3]unicode-properties and
   [4]unicode-names packages, which are representations in
   Haskell of various data in the Unicode 3.2.0 Character Database.

   experimental static blog engine in Haskell. jinjing [5]announced the
   initial release of [6]Panda, an experimental static blog engine written
   in Haskell.

   darcs hacking sprint, venues confirmed! (25-26 October). Eric Y. Kow
   [7]announced that two venues (Brighton, UK and Portland, Oregon, USA)
   have been confirmed for the [8]darcs hacking sprint on 25-26 October.

   darcs weekly news #2. Eric Y. Kow The second weekly issue of the
   [9]darcs weekly news has been published.

   xmonad 0.8 released!. Don Stewart [10]announced the release of
   [11]xmonad 0.8, featuring a general purpose "gaps" replacement, locale
   support, the ability to create your own configuration parsers, and
   various other [12]enhancements and fixes.

   POPL logo design contest. Don Stewart [13]forwarded a message
   announcing a logo design contest for POPL 2009. Dust off your magic
   markers/photoshop skills and get designing!

   ICFP09 Announcement. Matthew Fluet [14]announced [15]ICFP 2009, to be
   held 31st August to 2nd September 2009 in Edinburgh. ICFP provides a
   forum for researchers and developers to hear about the latest work on
   the design, implementations, principles, and uses of functional

   Fast parallel binary-trees for the shootout:
   Control.Parallel.Strategies FTW!. Don Stewart [16]announced that the
   Computer Language Shootout recently got a quad core 64 bit machine, and
   outlined a plan and some initial results for porting the Haskell
   entries to take advantage of the available parallelism.

   The initial view on typed sprintf and sscanf. oleg [17]announced an
   implementation of typed sprintf and sscanf functions sharing the same
   formatting specifications, which also led to some interesting
   discussion and alternative proposals.


   Generalize groupBy in a useful way?. Bart Massey [18]proposed changing
   the implementation of groupBy to extend its usefulness for predicates
   which are not equivalence relations.

   Splitting SYB from the base package in GHC 6.10. José Pedro Magalhães
   [19]initiated a discussion regarding splitting the SYB libraries out of
   the base package for GHC 6.10.

   The base library and GHC 6.10. Ian Lynagh initiated a [20]discussion on
   further splitting up the base package for GHC 6.10.

   Functional references. Tim Newsham began a [21]discussion on functional
   references and the possibility of merging the existing four or five
   implementations into something more standard.

   Types and Trees. Matt Morrow [22]wrote something about types and type
   representations, involving some commutative diagrams and some code. I
   haven't read it yet but it looks neat!

   Research language vs. professional language. Ryan Ingram started an
   interesting [23]discussion on the future direction(s) of the Haskell

   language proposal: ad-hoc overloading. Ryan Ingram [24]proposed adding
   ad-hoc name overloading to Haskell, prompting quite a bit of

   Top Level <-. Ashley Yakeley originally [25]asked whether there is any
   interest in implementing a top level "<-" to run monadic code. This set
   off a cascade of discussion the likes of which have been rarely seen on
   the Cafe. I would tell you what the discussion has been about but I
   must confess that I haven't read it.
