I was thinking of doing that as well, so I certainly would. I was
thinking that a traverse_path operation is pretty common, and any set of
objects implementing that protocol could be used .. be they a filesystem
tree, an XML document, or an object graph.

I still haven't figured out what the basic API should look like, but I
can imagine it being similar in complexity to Enumerable  -- a sort of
Traversable object.
