I know Dart isn't super widely used, but it's package manager, pub, is probably a good reference for this. We put a ton of work into it, and Dart users regularly single it out as one of the compelling parts of the Dart platform.

It hews pretty closely to Bundler's model (versions, version ranges, lockfiles, shared dependencies), though. So I don't know if it gives you much insight beyond "Yes, another language team things Bundler is on the right track."

Personally, I have a hypothesis that states that all programming languages either have a package manager that works like Bundler or will end up getting one.

Based on my work in buildpacks, I agree with the sentiment but I'm not as hopeful as you are.
