I'm having a hard time fully understanding how this works, but I don't think it is simply template substitution. I think it's creating multiple artifacts and completions from the one document. Because of that it's probably much easier if it is a language that can be easily introspected and doesn't support arbitrary expressions.

Okay fair enough then! I'd be interested to see what the rationale was, and if my knee-jerk reaction was unwarranted :)
