    # comments](https://github.com/bbatsov/rubocop#disabling-cops-within-source-code).
    # Obviously, those should be minimised and treated as a temporarily-tolerated
    # code smell; the long-term solution is to either make the code comply with the
    # the existing "cop" (rule), or disable that rule and write a custom rule that
    # enforces your modifications. (*PLEASE* leave a note of that in a comment atop
    # the affected code!)

    # Also, for each rule overridden here, leave at least a minimal note explaining
