Since the Java Posse has been talking about Scala a lot lately (E.g. episode 155), I felt compelled taking a closer look at Scala myself the last couple of days. Scala is a functional programming language that runs on top of the Java Virtual Machine (JVM). While it has its own interesting syntax-twists it is certainly easier to grasp for Java developers than for example Ruby (Purely from a syntax perspective). You can find more information on the Scala website.
I have not done much, yet. I downloaded it, installed the Eclipse plug-in and went through a good portion of the official Scala Tutorial. I also read “First Steps to Scala” at artima.com.
