It does. And it's a risk not keeping up with their pace of development. 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.

Interesting. Do you mean that Rome won’t perform type-checking in TypeScript/Flow, it just strips their type annotations (like their respective Babel plugins do today)? If so, is the idea that people might continue to use the tsc/flow binaries in parallel with Rome (e.g. if they want to validate types in a commit hook, or for in-editor linter-style warnings)?

I've been really looking forward to this source release since reading your tweets about it. Sorry it got posted to HN before you wanted it to, but thanks for making the code public at this stage.

I think so, in the same way that people use both Babel and TypeScript (or Flow) today. TypeScript/Flow check the types, while Babel simply strips them out when compiling the code.
