    when it's a multiple assignment method parameter.

  e.g. The locations of NODE_DVAR is fixed:

  ```
  a {|(b, c)| d}
  ```

  * Before

  ```
  NODE_DVAR (line: 1, first_lineno: 1, first_column: 4, last_lineno: 1, last_column: 10)
  ```

  * After

  ```
  NODE_DVAR (line: 1, first_lineno: 1, first_column: 5, last_lineno: 1, last_column: 9)
  ```
