Research direction
Start by reproducing the TypeScript sample in the repository's TextMate grammar and inspect the rules responsible for optional chaining and nested property access. Compare the syntax highlighting with the expected treatment of the sample; done means optional-chain expressions are recognized correctly across the supported editor grammars.

baz?: string;
}
