You may need to upgrade to the latest CVS version of Kawa.

Well, eval can return any kind of Java Object.  If you
restrict yourself to a limited class of expression, then
you'd get a limited set of "sorts of objects".

But it depends on the object - "dismantling" it may be
difficult.  Using a Consumer is one general approach.
AbstractSequence supports the ideas of a "pull
parser", but the API needs to be documented (and
possibly simplified).
