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: include.rb
    path of file: ./repos/ruby-packer/ruby/spec/ruby/library/set/shared
    
    the code of the file until where you have to start completion: describe :set_include, shared: true do
  it "returns true when self contains the passed Object" do
    set = Set[:a, :b, :c]
    set.send(@method, :a).should be_true
    set.send(@method, :e).should be_false
 
    
      def obj.hash; 42 end
      def obj_another.hash; 42 end
      def obj_another.eql?(o) hash == o.hash end

      set = Set["a", "b", "c", obj]
      set.send(@method, obj_another).should == true
    end

    it "is not checked using #==" do
      obj = Object.new
      set = Set["a", "b", "c"]

      obj.should_not_receive(:==)
      set.send(@method, obj)
    end
  end
end
