Welcome to issue 252 of the HWN, an issue covering crowd-sourced bits of information about Haskell from around the web. This issue covers the week of November 18 to 24, 2012. Quotes of the Week * rwbarton: edwardk now has Lens under Control * atriq: My son looks a bit like me, he can put away the plates after dinner now thanks to edwardk! * mgsloan: Lens got 99 operators, but a (|>) ain't one. * hiptobecubic: I feel like this program is just a bunch of glue and duct tape holding a bottle of nitroglycerine off of the ground. * xplat: Some software is worth trying; most is just plain trying. * edwardk: Control.Lens is my secret ploy to get everyone to give up on Haskell and just move on to Agda as they find the Haskell types too complicated by comparison. * rwbarton: alpha reduction is what happens when you let edwardk maintain your module * edwardk: er that was a tongue sticking out, not an operator suggestion Top Reddit Stories * [Haskell] Leaving Microsoft Domain: haskell.org, Score: 139, Comments: 24 On Reddit: [1] http://goo.gl/DnzZF Original: [2] http://goo.gl/eVcXi * Help Nikki (Game written in Haskell) jump on Steam!
