You'll need an attribute that determines the order. If your facts are
events, there's the timestamp. Otherwise, add a counter.
$latest: F( $c: counter )
not F( counter > $c )

then it throws java.lang.ClassCastException Error...i remember that there
can't be global object in the LHS ...so i need to adopt your idea , insert a
Date Object instead of using global one.
