Ideas for spec DSL

spec.rb

  describe "#inherit!" do
    # this would usually go in a before block and let and totally obfuscate what i wanna do:
    # also, this would be run once while the it blocks below are isolated.
    parent = Definitions.new([title, length])
    child = Definitions.new([stars])
    child.inherit!(parent)

    # make sure parent's definitions were cloned.
    # i'm fine with those it {} blocks:
    it { child.must_equal([stars, title, length]) }
    it { child[0].object_id.must_equal stars.object_id }
    it { child[1].object_id.wont_equal title.object_id }
    it { child[2].object_id.wont_equal length.object_id }
  end
