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: abstract_store.rb
    path of file: ./repos/stackneveroverflow/vendor/bundle/ruby/2.3.0/gems/actionpack-5.0.3/lib/action_dispatch/middleware/session
    
    the code of the file until where you have to start completion: require 'rack/utils'
require 'rack/request'
r
    
      def stale_session_check!
        yield
      rescue ArgumentError => argument_error
        if argument_error.message =~ %r{undefined class/module ([\w:]*\w)}
          begin
            # Note that the regexp does not allow $1 to end with a ':'
            $1.constantize
          rescue LoadError, NameError
            raise ActionDispatch::Session::SessionRestoreError
          end
          retry
        else
          raise
        end
