Fwiw, I use @CompileStatic it extensively and find it pretty good. There are the odd times when it generates a bizarre failure that I can't solve, but they are rare enough that I don't mind. I recently converted a whole project from Groovy to Scala hoping for performance benefits and found that my dynamic Groovy sprinkled with a few static compile hints ran faster than the Scala version. By the time I got the Scala version to the same speed as the Groovy version it looked a lot less like idiomatic Scala than the typed Groovy looked like idiomatic Groovy. So overall pretty happy with it, and I hope they keep improving it.
