def random_result
  # TODO: This logic is flawed in terms of choosing a truly "random" example!
  # E.g. /a|b|c|d/.random_example will choose a letter with the following probabilities:
  # a = 50%, b = 25%, c = 12.5%, d = 12.5%
  # In order to fix this, I must either apply some weighted selection logic,
  # or change how the OrGroup examples are generated - i.e. make this class work with >2 repeaters
