Yeah, I've heard or read Joe Armstrong talking about how Erlang process are like 'objects', but his brief cryptic comment needed something more. And I still disagree with it, because there's tons of interaction in Erlang that is not message passing.
I've glanced at it, but a language that sells itself as a Ruby-like language for the Erlang VM doesn't appeal to me. I really like Erlang, but don't care for Ruby. (In the procedural/OO/scripting niche, I strongly prefer Lua.)
I'll check it out again, though. If nothing else, it's an example of a real compiler written in Erlang, which is interesting in itself.
