Previous commit should have been:
  Use Ted's child walking interface to allow the dumper to walk the tree 
  in one place and only have node-specific callbacks worry about 
  formatting the nodes (instead of formatting the nodes plus walking the
  tree).

This commit eliminates now default cases by letting them fall through with
the normal visitor stuff.
