Comment (by pento):

 So, we have a bit of a problem, because PHP doesn't do method overloading.

 Changing the method signature of `Walker::walk()` caused an explosion of
 PHP warnings on WordPress.org when I deployed this change. The code still
 works as expected, it's just a sub-optimal experience.
