Feature: implicit subject

  If the first argument to the outermost example group is a class, an instance
  of that class is exposed to each example via the subject() method.
  
  Scenario: subject in top level group
    Given a file named "top_level_subject_spec.rb" with:
      """
      describe Array, "when first created" do
        it "should be empty" do
          subject.should eq([])
        end
      end
      """
    When I run `rspec ./top_level_subject_spec.rb`
    Then the examples should all pass
