[Haskell-cafe] Haskell Weekly News: Issue 252

Thu Nov 29 06:18:01 CET 2012

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
