You get
List<Any>from stringprefixesandsuffixescalls, which prevents assignments toList<String>. AddStringoverloads withList<String>return types and share the string implementations with the sequence fallback.I added regression tests for inferred return types, Unicode and empty strings, and calls through sequence annotations and untyped parameters. I ran
cargo fmt --allandcargo test --workspace; the workspace suite passed.AI disclosure: OpenAI Codex generated the implementation, tests, and PR prose.
