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
