Is there a way to do this in Scala?

Since Scala 2.9 you can use
sys.envfor the same effect:I think is nice to use the Scala API instead of Java. There are currently several project to compile Scala to other platforms than JVM (.NET, javascript, native, etc.) Reducing the dependencies on Java API, will make your code more portable.
