Scala has a annontation @elidable() that allows you to remove methods with a compiler flag.

With the scala REPL:

C:>scala

Welcome to Scala version 2.8.0.final (Java HotSpot(TM) 64-Bit Server VM, Java 1. 6.0_16). Type in expressions to have them evaluated. Type :help for more information.

scala> import scala.annotation.elidable import scala.annotation.elidable

scala> import scala.annotation.elidable._ import scala.annotation.elidable._

scala> @elidable(FINE) def logDebug(arg :String) = println(arg)

logDebug: (arg: String)Unit

scala> logDebug("testing")

With elide-beloset
