Welcome to issue 144 of HWN, a newsletter covering developments in the

The big news this week is the release of the Glorious Glasgow Haskell
compiler version 6.12.1, lots of exciting new improvements,
congratulations from the whole community go out to the devs, good work
GHC Team! 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.

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
