[antlr-interest] (qid) Qualified Identifiers

[Jim Idle]

Your code is copying the wrong thing. That example was about parsing:

 with X
  .y
 end with

Your code is also wrong as it should really be:

qid : ^(DOT qid qid?) // Second is only optional if supporting with x { .y
}
    | ID
    ;

Finally, it is unlikely to just be ID that qualifies, usually any
expression can do it.
