Welcome to issue 220 of the HWN, an issue covering crowd-sourced bits of information about Haskell from around the web. This issue covers the week of March 18 to 24, 2012.

Quotes of the Week

  • shachaf: Type classes are a scary story that you tell new Haskellers so they can go to sleep at night.
  • acowley: Parametric polymorphism is the inspiring story you tell them to get them riled up and raring to go. It's like Braveheart for programmers.
  • monochrom: the purpose of types is to ban more programs
  • rostayob: I was a type constructor, then I took an arrow in the kind
  • shachaf: @let otherfoolish = not otherwise
  • flebron: Monoidal objects in the monoidal category of endofunctors on a category. I took a small detour through tensor products to understand monoidal categories better, with one example of such a product.
    mauke: I have no idea what you just said
  • weexplat: starts a proposal to replace launchMissiles with atomicDestroyBiosphere
  • monochrom: rumour: SPJ will write a thick book "A New Science of Kind"
  • JonathanShapiro: [on abandoning BitC] "And I *still* don't believe in monads. :-)"

I wish Haskell programmers would stop saying "monoid*al* objects in a monoidal category", they're called "monoid objects in a monoidal category".
