Hello, this is what I did over my Christmas break. I've been taking some time to do other things, but plan on returning to it. But this absolutely works. Claude has written far more programs in my language than I have.

https://rue-lang.dev/ if you want to check it out. Spec and code are both linked there.

I ask because, as someone who uses these things every day, the idea that this kind of thing only works because of similar projects in the training data doesn't fit my mental model of how they work at all.

I'm wondering if the "it's in the training data" theorists are coding agent practitioners, or if they're mainly people who don't use the tools.
