Welcome to issue 83 of HWN, a newsletter covering developments in the Haskell community.

This is the "better late than never" edition. As an excuse I could tell you that my home internet service has been horrible (now fixed) and I was away from home for a few days with my wife celebrating our third wedding anniversary. But instead, I give you a link to the Uncyclopedia entry on Haskell. If you haven't already seen it, you should give it a read, being sure not to drink any milk at the same time, or at least pointing your nose away from the keyboard if you insist on drinking milk.
