The complaint about records is interesting because there aren't that many major languages that actually do records well. For a language of its age, it actually does records rather well. People sometimes forget that Haskell is older than Java and like Java it has a ton of baggage from its early days.

The tooling is definitely an issue for bringing in beginners, but as far as the build process goes if you're using docker and hosting your own package mirror (as you should be for a professional deployment) it's perfectly serviceable.
