You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: isolable_spec.rb
    path of file: ./repos/pakyow/support/spec/features
    
    the code of the file until where you have to start completion: require "pakyow/support/isolable"

RSpec.describe "isolating objects" do
  shared_examples "isolable" do
    let(:isolable) {
      isolable = Class.new do
        include Pakyow::Support::Isolable
 
    
          def isolate_object
            isolable.isolate(State) do
              def self.extended_through_isolated; end
            end
          end

          it "extends the isolated object" do
            isolate_object

            expect(get_isolated_object).to respond_to(:extended_through_isolated)
          end
        end
