I've been working with scala for the last 2 months and I like it. The things i don't love are: the long compile times (lots of time wasted here), the lack of a community accepted/official coding practices - if sbt by default would run scalastyle on packaging/testing, that might help on enforcing a consistent set of good common practices on community code.
It's just been released, but I like the idea of adopting a tool in the likes of gofmt. Coding style discussions are such a bike-shedding magnet, it's good if you can just not think about it (and are able to follow it anyway, regardless of IDE).
I'm the author of scalafmt, happy to hear there's interest in the project! Scala has a very rich syntax. I remember first coding in Scala being unsure where to put newlines or how far to indent. My hope is to make that problem go away.
Scalafmt is indeed new, just released 0.1.0 last week. However, it's already become useful for me with the IntelliJ plugin. Scalafmt is practically my full-time job for 2 more months so you can expect it to get more mature soon. Feature requests and bug reports are very welcome.
