All Implemented Interfaces:

public class ElidableResultNode
extends RubyNode

This node has a pair of children - one required and one elidable result. The required node is always executed, but its result is discarded. Therefore it should perform some useful side effects. The elidable node is executed, and its result value returned, if an execute method with a non-void type is used. It is not executed at all if a void typed execute method is used. Therefore it should not perform any observable side effects.
