[antlr-interest] ANTLR 3.0 tree construction proposal

For unit testing, I've found that I can write dummy "productions" in
tree grammars that return the input tree to test:

   // this "production" generates the tree to be traversed
   unittest_input: { ## = #( #[S,"S"], #( #[R,"R"], #[E,"E"]) ); } ;

So a unit test framework is
  1. call unittest_input to generate the input tree
  2. call the production to be tested
  3. compare the tree produced with the expected tree

It's enough for unit testing.
