object EitherValues extends EitherValues
Companion object that facilitates the importing of ValueEither members as
an alternative to mixing it in. One use case is to import EitherValues's members so you can use
left.value and right.value on Either 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).
Type in expressions to have them evaluated.
