As I understand it, the goal is not for Rome to do type-checking, but just for it not to choke on TypeScript's syntax (i.e. what Babel does): > Supporting those "compilers" is just supporting their syntax, which both fortunately already have very good compliance test suites because other tools like Babel already reimplement their syntax anyway.
