      NoMethodError (undefined method `include?' for nil:NilClass)
      

      The issue appears to be that YAML.load calls respond_to? on the Regexp::Raw instance prior to the instance being initialized, and respond_to? then attempts to figure out integer regexp options from the string options but because the string options aren't set yet, this fails with an exception.
