Hello my Lisping friends,
I've already told some of you this, but I've started on a project to bring Erlang's light-weight, message passing concurrency to Common Lisp. Today I've finished completely overhauling my website, and I've created a project website for Erlisp in the process. (See: http://www.dirkgerrits.com/erlisp/) Here's a brief summary:
Why is it that Common Lisp is better than "mainstream" languages in a lot of ways, but not in parallelism and distributed programming? Is it just because threads with shared memory and locking are the best we can do for parallelism, and because socket and RPC libraries are totally adequate for distributed programming?
I think the answer is no. Some older Lisps and a few younger, non-Lisp languages like Erlang have intriguing approaches to concurrency that are easier to use and less "low-level" than this industry best practice.
Erlisp is my attempt to bring some of these ideas to Common Lisp, and perhaps develop some new approaches in the process.
Phase 1 of this project will involve bringing (most of) the features of the Erlang programming language to Common Lisp. Erlang is a small but powerful functional, parallel, and distributed programming language originally developed at Ericsson for use in the telecom industry. It's been really successful as a parallel and distributed programming language, and is pretty Lisp-like for a language with syntax, so it seems like a good starting point.
Phase 2 is much bolder and involves doing for models of parallel and distributed programming what the CLOS MOP did for object systems. The design of such a metaobject protocol is a hard and evolutionary process with which I have absolutely no experience, so this is very much a long-term goal.
So far, there is no code to speak of. Just Erlisp's roadmap, describing the basic plan of attack for its realization, and a list of references to relevant articles, books, etc.

I have two links to offer (I don't know enough about Erlang to check whether they are relevant):

Thanks, I'll add them to the references page ASAP. By the way, you may not have realized that, but you did a 'reply to all', thereby e-mailing not only the mailing lists, but also some of my personal friends. ;) Reply to all to this message should be safe though.
Kind regards,
