I think it's a bug related to the way the current implementation
identifies where the property ends.  (The second example uses the same
list as the value, whereas the first example uses 3 different lists,
although they have the same contents.)

The current code is not yet ready for prime time IMO, and Lars
intended to work on it soon.  Stay tuned.
