> Rather than raise {{IllegalArgumentException}}, if {{select}} cannot find the label, it should return {{null}}.  This is preferable because of the difficulty of dealing with exceptions during traversal.  It is not always indicative of a static flaw in the traversal, since conditional logic in the traversal may bypass certain {{as}} steps.
