Awesome!
Do you have any interest in integrating this with Avocado? (http://avocadojs.com - it's a Self-like environment I've been building for JavaScript.)
I've been sticking with standard JavaScript syntax so far, but I think it'd be really cool (and maybe make me feel a bit less homesick ;) if I could write real Self code inside Self-like outliners running on top of my web browser's Self-inspired JavaScript VM.
