The feature works by accepting additional arrows to indicate the relative depth from the current node's perspective at which to search, like in r => r => r.name == "ChildTag".
It can help avoid ambiguous results and speed up searches tremendously.
Mixing in ternary operators allows to decide for every visited node whether or not to recurse into its children.
An example for this approach is given in nested-lambda-demo.html.
