Rule implementation that calls a method on the root object on the stack, passing the top object (child) as an
argument. It is important to remember that this rule acts on end.

 This rule now supports more flexible method matching by default. It is possible that this may break (some) code written against release 1.1.1 or earlier. See AbstractMethodRule.isExactMatch() for more details.
