Subject: YAML::Syck::Map.children_with_index has a non-useless mode?

Ruboids:

I have some dirt-simple YAML, and I need to traverse the object model 
returned by YAML.parse().

So if the top-level object is a Map (corresponding naturally to a native 
Hash), how do I get the keys and values?

Try this:

    map.children_with_index.each do |kid, key|
            p kid
            p key
          end

The 'key's come out healthy Scalars, but the 'kid's are always nil! 
Permutations involving map[key] and map.at(key) also return nil, because 
that's what

Oh why can't I get non-nil kids from my map?? (Without using map.value[key] 
to go down to the Hash - because I don't want to!)
