Welcome to issue 272 of the HWN, an issue covering crowd-sourced bits
of information about Haskell from around the web. This issue covers the
week of June 23 to 29, 2013.
Quotes of the Week
* kmc: johnw: I'm rejoining this channel after months away just to
tell you how incredibly wrong you are that monads are the "core
concept" of Haskell
* dmwit: semigroups are monoids with an identity crisis
* olsner: I think doing eta something means to make it more or less
pointless. But I don't recall which eta does what
* mm_freak: Oleg knows what's at the end of foldr f z [1..].
* copumpkin: it's like grasping desperately for the rope of induction
as you fall down the bottomless pit of coinduction
