That's a good suggestion. I didn't think of that. But thinking about it, I guess I don't want to bother the OPs inbox. If they are interested, they can get in touch.

I disagree. When I post a new language, and someone shares a link to a related language, those are often the most valuable comments.
Validating, defining, using data: sound like things Tree Notation syntax is perfect for. Cue's semantics are great, and presentation and execution, I just think potentially a syntax switch is worth exploring. I understand the strategy to be able to parse JSON as cue, and that's probably the way to go for now, but in the future Tree Notation syntax might offer compelling advantages.
