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: each_positional_argument.rb
    path of file: ./repos/leftovers/lib/leftovers/processors
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Leftovers
  module Processors
    class EachPositionalArgument
      include ComparableInstance

      def initialize(then_proce
    
      def process(_str, current_node, matched_node, acc)
        positional_arguments = current_node.positional_arguments

        return unless positional_arguments

        positional_arguments.each do |argument_node|
          @then_processor.process(argument_node.to_literal_s, argument_node, matched_node, acc)
        end
      end
