The TypeScript type checker is only used to type check the Rome source code. The compiler is not used at all.

Do you plan to self-host at some point, and get rid of the dependency on the (external) TS compiler?

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.
