That makes a lot of sense. ASTs tend to be a very dumb but fairly verbose data structure. And, in C in particular where everything is more verbose, there ends up being a ton of boilerplate in the AST nodes.
In a language like Ruby with a very rich syntax, you end up needed a ton of different AST nodes.
Generating those from a simple declarative format makes maintaining that much easier.
