Rather than commenting on the code provided, here are the two biggest wins I've had recently with Haskell. Both of these are part of a physical modeling project. 1) uu-parsinglib - simple to use and automatic error correction. I really, really enjoy working with this library, and how often can you say that? 2) STM - the original design reads a system and all inputs from a config file, then runs the system and produces output. I wanted to build the system from a file but collect inputs and produce output in real-time. After a few small adjustments, a few TVar's and a TMVar, and three forkIO's, it was working. One concern is that the engine (which is computation-intensive) shouldn't block waiting for input, it should just continue on and catch up later. With STM, this can be expressed as: atomically $ getInputs inputTVar `orElse` return () and there's the desired behavior. Couldn't be easier. John From: Blake Rain <blake.rain@gmail.com>
Dear Haskellers,
I thought I'd take some time to share something of my weekend with you all. Not because of anything new, but because it is a feel-good example of Haskell being win. A good read for Monday morning, perhaps.

Now over to you guys! What experiences have you had which make you glad you use Haskell? Anything make you smile recently?
