Sometime you'd get an error that's not the root cause (and as scala is statically typed and uses type inference, this can happen often when making a large refactoring).

ScalaIDE has some official support, but since I've installed it the JVM crashes (that is, I get the OSX's crash dialog, not even Eclipse's). There's a NetBeans plug-in on the way (<a href="http://nbpleasureplugin.com/" target="_blank" class="">http://nbpleasureplugin.com</a>). As IntelliJ is expensive, buggy, eats RAM and CPU and is generally annoying, I currently use Sublime text and the console.
