- This is cleaner than vendoring a whole bunch of new gems and pinning `psych`.
- Thanks for the pointer, Bo!
- It doesn't work, though?

- Byebug was introduced in [2020](https://github.com/Homebrew/brew/pull/7577) for hooking into tests for debugging.
- It does not work anymore in so far as it does not stop at breakpoints when following the instructions to trigger them in tests.
- The preferred way of doing RBI generation is via Tapioca. So I am
trying to stop being intimidated by it, by learning how it works.
- This is very WIP still, currently failing with the following message
because the `module` name is missing in the generated RBI file.
```
There are parse errors in the generated RBI files.
Errors:
sorbet/rbi/dsl/tty.rbi:8: unexpected token tNL (2001)
sorbet/rbi/dsl/tty.rbi:64: unexpected token "end" (2001)
```
