This project was more of an experiment.

I would check out https://github.com/eomii/rules_ll if you want to use modules with bazel

I see... well, it's linked from isocpp.org, which seems pretty official. It might make sense to indicate that this is not supposed to be an "official" example, it's just an experiment that might not actually work for people.
