<div>Welcome to issue 252 of the HWN, an issue covering crowd-sourced bits</div><div>of information about Haskell from around the web. This issue covers the</div><div>week of November 18 to 24, 2012.</div><div><br></div><div>
Quotes of the Week</div><div><br></div><div> * rwbarton: edwardk now has Lens under Control</div><div><br></div><div> * atriq: My son looks a bit like me, he can put away the plates after</div><div> dinner now thanks to edwardk!</div>
<div><br></div><div> * mgsloan: Lens got 99 operators, but a (|>) ain't one.</div><div><br></div><div> * hiptobecubic: I feel like this program is just a bunch of glue and</div><div> duct tape holding a bottle of nitroglycerine off of the ground.</div>
<div><br></div><div> * xplat: Some software is worth trying; most is just plain trying.</div><div><br></div><div> * edwardk: Control.Lens is my secret ploy to get everyone to give up</div><div> on Haskell and just move on to Agda as they find the Haskell types</div>
<div> too complicated by comparison.</div><div><br></div><div> * rwbarton: alpha reduction is what happens when you let edwardk</div><div> maintain your module</div><div><br></div><div> * edwardk: er that was a tongue sticking out, not an operator</div>
