6702 - readonly in .d.ts files Problem: typescript@next users can't give their generated .d.ts files to 1.8 users What's the difference between this and e.g. union types? This one doesn't require any opting-in Not universally true -- some expressions became union types, for example Options Commandline flag Tool (regexp or something smarter) Don't emit readonly in .d.ts until 2.0 ships, or "later"
