Discussion on: The Case for TS+

because changing syntax would break compatibility with tools like eslint or prettier, additionally you are supposed to be able to integrate TS+ progressively in code potentially even directly for projects that have types maintained separately (so you need something that you can write in d.ts which is add only and doesn't break any standard TS/JS). TypeScript itself is progressively thinking more and more of types as comments and their recent TC39 proposal goes in that direction too. I can see how it may be perceived as non friendly to use but in practice our feeling after having built huge codebases like with it is that it is indeed very friendly to use and those comments only end up representing a small portion of your code.
