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. :)
