This appears to be a bug in rubocop.

* It's complaining about conditional assigment in a method where no
  assignment is being done, instead we are comparing two objects using
  the triple-equals method.

  ```ruby
  case other
  when IPRange
    @range === other.range
  else
    @range === other
  end
  ```
