Lambda the Ultimate

As of about a week ago, Jonathan Blow (creator of various well received games such as Braid as well as various PL efforts) has pair of talks on twitch.tv (later both put on youtube) where he issues a call to arms for game developers to design a new programming language around their concerns. He discusses what he sees as some of the shortcomings of existing languages that are supposed to be C++ replacements, and some of the requirements he feels game devs have. There was a Q&A session as well.
The talks are more practical than PL theoretical, but interesting (and occasionally frustrating) never the less.
