The point about this site and Ark is that they (pg and rtm) practice what they preach. It is, basically, a real project based on philosophy from famous "beating an average" essay and the "On Lisp" books - quick, bottom-up process of bootstrapping of a several layers of DSLs (idea popularized by SICP and refined in On Lisp) - with a new dialect of Lisp as a by-product.) Everything in a half of Mb of text.

OK, they reused mzsheme's runtime, because runtime is hard (even clojure delegated everything to JRE) but nevertheless, Arc and this site are remarkably successful examples of real world project with all the benefits of dynamic languages.

Sorry for the delay, we had a quake that day.
