A more developed variant with these goals, that got discussed a fair bit in the arc forum, is https://github.com/arclanguage/arc-nu https://github.com/arclanguage/arc-nu. It hasn't received much kicking on wheels by anyone other than its author(s), though, so be prepared for some rough edges if you decide to try it out. In the long term I think it might be much nicer than the original prototype. (Disclosure: I'm one of the owners of the https://github.com/arclanguage https://github.com/arclanguage community. Also check out https://arclanguage.github.io https://arclanguage.github.io, which is a more up-to-date statement of the Arc state of the world.)
