My basic objection to this style is that if the XML
document is arbitrarily deeply nested, your code has to
be too: elements within elements are represented in the
code as loops within loops.  Alternatively, you have to use
an explicit stack to keep track of the current Iterator

I just snarfed the YAML spec today and look forward to
