I have been experimenting with using Yesod to throw together a web application or two. My experience so far has been broadly positive—if you like computers to check things for you, I recommend it. ((assuming you like deciphering compiler error messages when the computer says no, that is)) That said, watching the full chain of dependencies fly past was moderately entertaining: ((for a quiet Wednesday morning…))
