Style/CaseEquality:
  # The code uses `===` a lot to compare a regex to a string, but it's not clear that
  # switching to `=~` is always safe, because in some cases the value could be a regex
  # or a string and `str1 =~ str2` isn't valid. Whoever enables this cop should carefully
  # review and test each of these.
