I think you have misunderstood the implementatation of the ptree. There are
no "upward" links in the structure so there is no way for a node to know its
parent or root.

Personally I think it would be a good idea to let each node carry parent
and/or root information. That way you could store tree-wide information (e.g.
separator, locale, source) in the root.

Only downside I can think of is O(N) swap instead of O(1).
