FYI - one downside of returning the appended object as opposed to self 
is that the variable node above is the "bar contents" node.  Thus you 
have to write:

puts node.parent.parent.

I find that surprising.  It would be nice if node was the top node.

Thus in the example it would be nice for << to return the child object 
in some cases and self in others.  Sigh.

Anyone see a way of getting the best of both worlds?
