Otherwise, this week has been quiet, with some interesting discussions about associated types and the new GHC, and some excellent new packages announced. Finally, due to the incoming holidays, there won't be an HWN for the next two weeks, I'll see you Haskellers in 2010, until then, your Haskell Weekly News!

Quotes of the Week
- yrlnry: <byorgey> yrlnry: just some lady who had a lot of money and decided she wanted poor grad students to have some of it after she died... pretty nice of her, actually <yrlnry> senile dementia, more likely.
- Philonous: A 'newbie', in Haskell, is someone who hasn't yet implemented a compiler. They've only written a monad tutorial.
- kmc: Right, for example Either (pun not intended)
- kmc: One thing I've learned from open-source software is that if you invent enough wheels, one of them will turn out to be round and capable of rolling.
- PhilipWadler: To see that "in" and "out" are inverses, stare at the following diagram
- kmc: Data.Map is like a C++ STL map<k,v>, without the suck
- edwardkmett: Most monad tutorials are written by people who barely understand monads, if at all, but unfortunately nothing can stop someone from writing a monad tutorial. We've tried, there was blood everywhere.
- Cale: A small category is a monad in the 2-category of spans of sets.
