Is Arc open source?

The language, yes[0], but AFAIK the maintainers don't take pull requests.

Arc has a public fork called Anarki[1], which is built on Racket[2]. The Anarki version of the forum differs from the Arc forum, which differs from HN's own custom instance, which is closed because of various YCombinator business reasons.

And to be a little more specific (because I really like Arc), the releases are very rare, and minor at this point. I would be surprised if the Arc that was running HN was the latest released version of Arc, the news library notwithstanding.

For example, the latest release, Arc3.2, came out in 2018, and was relatively minor (http://arclanguage.org/item?id=20772). Arc 3.1 was released in 2009 (http://arclanguage.org/item?id=10254).
