I think that one of the things that Perl6 will bring is continuations. This will enable you to treat a tree traversal in the same way as any other list.

For example:

for $tree.depth_first_traversal("process") -> $node
{
...
}

There would be no need to obscure the client-code with the details of hierarchical navigation. (Question: can I use C<yield> inside a recursive implementation of the iterator?)
