I might finally have to take a look at Grails now that there's static type checking. Do I need to wait for a new release of Grails to use Grovvy 2.0 with it or can I do that now? Also, I'm curious if it can be turned on globally when calling the compiler instead of having to annotate all of my classes with @CompileStatic?
