That looks very cool. I'll look at it, and maybe steal a few ideas :). I've been working on a data language myself in my spare time, mostly concentrating on generative structures like conditionals and loops and a syntax-independent data model. But Piqi looks to be a lot more ambitious, not to mention mature.

Thanks! Feel free to reuse as many ideas as you like :) It took me more than 2 years to get it there -- it is by far the toughest system I've ever designed.
