Given that Go modules can depend on private interfaces that specify only the methods they need, dependency injection of the pass-dependencies-to-the-constructor style seems almost built in. Not automated as such, but easy.

This is the way. Make it explicit, obvious, and debuggable. I much prefer to pass my dependencies around, and have a bit of duplicated code to programming in a dynamically typed configuration language and trying to figure out why the eff I’m getting runtime errors.
