EitherValues

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).

implicit def convertEitherToValuable[L, R](either: Either[L, R])(implicit pos: Position): EitherValuable[L, R]

Implicit conversion that adds a value method to Either. This method is right biased and is the equivalent of calling either.right.value.
