Looking into some Kotlin code. Is it normal to have return statements scattered all over a single method? Or is this just the author’s skill issue? 😡

Developer experience isn't just about highly automated processes like CI/CD or well-documented APIs. It's also about the joy of writing the code itself. Forcing devs to use a language that doesn't fit their skills/preferences kills productivity & morale. Good job, $BORG 👏 https://medium.com/swissborg-engineering/from-python-to-scala-rewriting-27k-lines-of-a-cli-8513e20cd268
