how best an rspec tradition matcher exam opening control rails app

ok, instead minute whole garland opening control specs, duplicating opposing spec files, i'm looking emanate tradition matcher. instead this:

describe "access control" do
  "should hinder opening non-logged-in users"
  "should hinder opening normal users"
  "should hinder opening editor users"
  "should hinder opening admin users"
  "should grant opening super admin users"
end

i wish something this:

lambda do
  :index
end.should have_access_control(:allowed => [:super_admin], :disallowed => [:admin, :editor, :user])

are there any examples suggestions i doing something this?
