RSpec's New Implicit Subjects

In case you missed the announcement, RSpec now supports this badassery.

describe Person do
  describe "born 19 years ago" do
    subject { Person.new(:birthdate => 19.years.ago }
    it { should be_eligible_to_vote }
    it { should be_eligible_to_enlist }
    it { should_not be_eligible_to_drink }
  end
end
