The actual lines look like this:
answer_statement: ANSWER expr answer_btn_list { ... }
| ANSWER_FILE { ... }
| ANSWER_FILE expr { ... }
| ANSWER_FILE expr OF TYPE expr { ... }

answer_btn_list: WITH answer_btn_list_oneplus { ... }
| { ... }

answer_btn_list_oneplus: answer_btn_list_oneplus OR expr { ... }

expr: ...

ANSWER expr WITH expr OR expr
