Welcome to issue 257 of the HWN, an issue covering crowd-sourced bits

of information about Haskell from around the web. This issue covers the

week of January 27 to February 02, 2013.

Quotes of the Week

* shachaf: Everyone forgets about Agda Lovelace, the first

constructivist.

* applicative: I have my new ghc and am reinstalling my feeble world

* wuttf: My world is starting to feel like isToyLanguage x = x /=

Haskell

* PenguinOfDoom: Being enlightened gentlemen, we split all

programming languages into two groups, sucks and doesn't-suck and

put all of them into the first group.

* Taneb: lens has got to be the only library with more contributors

than people who know how it works

* shachaf: I like to put all my application's modules under GHC.*

That's because I use the GHC API, and I want them not to conflict.
