    message:
      Detected useless comparison operation `$X == $X` or `$X != $X`. This will always return 'True' or 'False' and therefore
      is not necessary. Instead, remove this comparison operation or use another comparison expression that is not deterministic.

    message:
      Detected useless if statement. 'if (True)' and 'if (False)' always result in the same behavior, and therefore is
      not necessary in the code. Remove the 'if (False)' expression completely or just the 'if (True)' comparison depending
      on which expression is in the code.
