I've definitely found LLM code to be syntactically/semantically correct in one-shot pretty much all the time. It's usually the functional specification/behaviour that's found wanting.

Typing probably makes sense where memory-correctness needs to be enforced (e.g. Rust), and inferring those semantics require a much wider context. But memory-correctness isn't really something that afflicts BEAM languages.
