[antlr-interest] creating root nodes in rules

[Tarun Khanna]

consider the following grammar

some_expr:
id 
(
DOT^ id
|!
LPAREN expr RPAREN
{
#[APPLY, "FuncCall"];
}
)*


you see how the first option creates DOT as the root node for the tree 
constructed so far. I need to do something similar for the second option 
however I need to create a new node and then make it the root exactly like 
DOT is made root in the previous alternative. Any idead how this can be 
done?

Thanks
