I'm sure the syntax isn't right, but you should get the idea. In your
interface rule create a tree to populate and pass it as an argument to
the using rule:
interface:
{AST usingTree = #(USING);}
...
| using[usingTree]
...
;
using[AST usingTree]!:
"using" i:ID {#usingTree.append(#i);} //not sure of actual method to
append a node off the top of my head
;
