On January 29th, they finally released a first-draft implemention. Although billed as experimental and subject to change, it’s still something a lot of people will want to play with. Those of us who for whom programming in Lisp is a cherished memory, a kind of long-lost Eden to which we hope one day to return, are interested to see if Arc can become what we’ve been hoping for: a Lisp-like language that’s caught up to the modern world and that gathers enough developer momentum to flourish.

Unfortunately, the Arc web site, arclanguage.org, doesn’t answer the very first question most potential downloaders would ask: is it open source?, or as we used to say, is it free software? The site not only doesn’t say what license the software is released under, it doesn’t even state clearly that the software is open source! I finally downloaded the package itself and poke around inside to find out:

This software is copyright (c) Paul Graham and Robert Morris. Permission to use it is granted under the Perl Foundations's Artistic License 2.0.

Okay. So it’s open source, albeit under the least open-source of all the open source licenses. Sigh. I normally wouldn’t even go to the trouble of downloading the software to find that out, I only bothered because I was already quite interested in Arc.

I’d post on their mailing list a comment about the hidden license problem, but they apparently don’t have a mailing list. Instead, they have low-functionality web forums, and it looks like the only way you can interact with the community is through that forum interface. This is a pity: the thread is the fundamental unit of information on the Internet, and there’s no reason to force people to use one particular interface to access a set of threads. Perhaps some people like web forums, but others would prefer to access the threads via their mailreaders. If I have to use a web interface just to talk to a community, it makes me less likely to join that community, because I’ll start to associate participation with wrist pain. Let me choose my own interface, please.

Speaking of which, how about a bug tracker? Or any of the other tools that are now standard for open source projects? Some of the forum posts indicate that there’s a version control repository somewhere (using git), but the web pages don’t point to it, at least not as far as I could see. So those looking to follow development in real time will have to hunt around.

Given that the web site says “we’d like to encourage a sense of community among Arc users”, this is all a bit disappointing, and puzzling. It’s like they don’t actually want to build a community, which would be fine (it’s their project), but then why declare otherwise?
