Because, in the real world, that example looks something like

  def broken(intelligence_level):
    if intelligence_level < 100:
      return dumb_down(intellegence_level)
    else:
      return make_harder(intelligence_level)
  broken(op.iq)

Pylint, pyflakes or some other such linter should catch it, but this
happens ALL THE TIME in actual development, occasionally leaking into
production.
