[antlr-interest] ast problem

[Bryan Ewbank]

We need more information.  What is the root node to be, since it is
not the typedef?

If you have something like this:
   statement
      : ...
      | TYPEDEF^ a:name b:type
      ;

Then a and b are children of the same node - the TYPEDEF node.  So,
you can overwrite the name and type of that root node if you want, or
you can leave it.

The sequence you want is probably
      #( #[TYPE,"NAME"], #a, #b );
but you already have that - with the TYPEDEF as the root of this small tree.

Hope this helps,
- B
