+* The data flow library now adds intermediate nodes when data flows out of a function via a parameter, in order to make path explanations easier to follow. The intermediate nodes have the same location as the underlying parameter, but must be accessed via `PathNode.asParameterReturnNode` instead of `PathNode.asNode`. `@kind path-problem` queries may have their expected test-output changed as a consequence.
