Oh, from CHANGES.txt:

* Added AST construction for tree parsers including -> rewrite rules.
   Rewrite mode (rewrite=true) alters the tree in place rather than
   constructing a whole new tree.  Implementation notes:
   ...

* got tree rewrites working in tree grammars.  It builds a completely  
new
   tree from old tree; i.e., you get two trees in memory.  W/o a rewrite
   rule, the input for that rule is duplicated and returned. -> w/o  
elements
   to the right means don't return anything; i.e., delete.  Ooops...way
   harder than I thought.  Real implementation notes above.
