I'm surprised you've not heard of the author (Sean Baxter). He's pretty well known among people who are interested in c++ standards proposals. He single handedly wrote his own C++ front-end and then proceeded to implement a butt load of extensions which other members of the committees poo-pood as being to hard to implement in the compiler. Every couple of weeks he implements something new. He's a real joy to follow.
