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
