Dotty has a number of breaking changes, as well as deprecating many patterns in favor of new language features. This creates a huge amount of technical debt for users, which we’ve been told is solved by a rewriting tool.
What is the status of this tool? How many rewrites does it already do and how many does it not do yet, and how much real-world code has it been tested on?
Also, is there a way to test that even if the rewritten code compiles, that it still means the same thing?
Is the UX polished or is there a ways to go from being a tool that works to a tool that works seamlessly enough that people won’t see it as a burden?
What is the roadmap and timeline for it to be fully production-ready?
