Over 6 years ago Paul Graham told the world that he was working on a new programming language called Arc. It would be some derivative of Lisp, but otherwise not much was known about it. Graham is the author of 2 books on Lisp and a popular series of essays on topics ranging from programming to startups. As he had been mostly quiet about Arc for such a long period of time, many people have forgotten about it or dismissed that it would ever come to light. Two weeks ago Paul announced the initial version of Arc and made it public. I haven't had a chance to look at it yet but I intend to. If you are interested, you can find information at arclanguage.org. There seems to be some excitement building around it. Only time will tell if it can build a user base or if it fades like so many other new languages.
