But you miss understand...  I'm not suggesting a path object be a tree, 
but it should/could be used as a key for accessing data stored in a tree 
structure.

The path object it self would be much the same thing as what is already 
being discussed.  Using it as a key to a tree data structure is an 
additional use for it.
