Having similar experience with my experimental code generator to Rust. Every time a yet another example does not work, Claude fixes it. However, I am curious whether it would converge to a bullet-proof solution, or I have to carefully read the code and come up with proper abstractions.

Are you using syn to pretty print a tree, or concatenating strings?

I think it helps having an intermediate tree where every value is valid rust code (not just synctactically, but it compiles and runs fine) helps a lot. Like an IR for your transpiler

if you're trying to write rust without thinking about the abstractions then yeah, its probably non-terminal. I would strongly suggest making the broad strokes yourself and letting it fill the details.
