object PartialFunctionValues extends PartialFunctionValues

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

$ scala -cp scalatest-1.7.jar
