To be honest, the real issue with LX / XL / Tao3D is that I never ever really "finished" any implementation. By the time things were working, I had new ideas and broke things again. So except for Tao3D, I never really delivered a version of the language that was solid enough.

I'm trying to work on that now, which is why I'm presently spending so much time on documenting where I want to go. The idea is that if I first write a "spec", then a community can build to implement it, and it's not just my own (limited) time.

So if you are interested in helping right now, I'd say: read the doc (in progress) and send comment / doc fixes.
