Welcome to the 217th issue of the HWN, a newsletter covering developments in the Haskell community during the week of February 19 to 25, 2012.
Quotes of the Week
- nand`: oh, wait, ANSI is the physical layout
- cmccann: some programmers have a problem to solve and think "I know, I need an existential type." now they have another problem, but can't solve it because all they know about it is that the problem exists.
- Philippa: The only data type is Nat! (Which succs).
- hpc: peano arithmetic SSSSZ life
- cmccann: unicode snowman is a valid identifier in Haskell, BTW
- Jafet: Haskell is an imperatively functional abstract enterprise programming language template
- Cale: Array is immutable boxed
Cale: UArray is immutable unboxed
Cale: IOArray is mutable boxed
elliott: IOUArray is an array of debts. - c_wraith: It [C] frees you to use whatever data structure you want, by providing you none!
- Brandon Allbery: If you absolutely insist on shooting yourself in the foot this way in Haskell, it can be done; but there is no reason Haskell should make it *easy* to do so. That's C's superpower. :)
