To code smell, or not to code smell: that is the question

gistfile1.rb

  # old
  def build_form_response
    form_response = self.form_responses.new

    self.questions.each do |question|
      form_response.answers.build(:question => question)
    end

    form_response
  end

  # using tap
  def build_form_response
    self.form_responses.new.tap do |form_response|

      self.questions.each do |question|
        form_response.answers.build(:question => question)
      end

    end
  end
