OptionValues

object OptionValues extends OptionValues

Companion object that facilitates the importing of OptionValues members as an alternative to mixing it in. One use case is to import OptionValues's members so you can use value on option in the Scala interpreter:

$ scala -cp scalatest-1.7.jar
Welcome to Scala version 2.9.1.final (Java HotSpot(TM) 64-Bit Server VM, Java 1.6.0_29).
