Agreed. I'm using IntelliJ Community Edition with Scala plugin. It works really well. Only settings I've changed were setting the font to Source Code Pro and turning off spell checking.

I'm absolutely loving Scala right now. I was writing a lot of stuff in Go until I started a new project that needed to leverage some Java libs. I had been wanting to try Scala, so I went with it instead of Java (or Clojure, etc).

I liked Go for it's elegant concurrency, ease of deployment, and fast compiler, but Scala's type system and composition with for comprehensions is really nice.

Java interop is pretty seamless so far. Scala has nice primitives for wrapping null and exceptions in safer ways and eliminates a lot of ugly x != null checks everywhere.

Coming into it, I'd heard that Scala was hard to learn, but I didn't find that to be true. I was only vaguely familiar with pattern matching, monads, traits, ADTs, etc from playing with Rust, but I found plenty of good resources for learning Scala.

I really found this series of blog posts to be helpful: http://danielwestheide.com/scala/neophytes.html
