   Welcome to issue 181 of the HWN, a newsletter covering developments
   in the Haskell community. This release covers the week of May 1 to
   7, 2011.


   Last week I failed to note the announcement [http://goo.gl/ApClU]
   of a new version of Leksah (0.10.0). If you haven't yet, give
   Leksha a test run and send some feedback!

   Ketil Malde started a thread [http://goo.gl/Prlu2] about Robert
   Harper's thoughts on monads and laziness.

   Hakim Cassimally extended an invitation [http://goo.gl/QIjcF] to
   anyone living in the Northwest UK for Tuesday May 31st to Geekup's
   first ever "Functional Programming Night".

   Andy announced [http://goo.gl/uCEn1] a new release of Manatee

Quotes of the Week

   * hpc: [SPOILER] You can check wikipedia for the definition of
     fibonacci sequences if you get stuck after half an hour

   * pmetzger: it is always possible to make an algorithm
     slower. just give it to a CS freshman to code up.

   * kmc: ghc -XMixfixOperators -XDependentTypes -XMakeMeASandwich

   * pmetzger: I have my password tattooed to my forehead. that way
     when I forget it others can tell me what it is.

   * alexbagel: i find that my first 26 variables are always easy to
     name. after that it becomes a bit harder.

   * Eric Kow: Haskell is a good fit for me because I tend to
     practise Doh!-oriented programming
