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    filename: outdated.rb
    path of file: ./repos/brew/Library/Homebrew/cask/cmd
    
    the code of the file until where you have to start completion: module Cask
  class Cmd
    class Outdated < AbstractCommand
      option "--greedy", :greedy, false
      option "--quiet",  :quiet, false

      def initialize(*)
        super
  
    
      def self.list_if_outdated(cask, greedy, verbose)
        return unless cask.outdated?(greedy)

        if verbose
          outdated_versions = cask.outdated_versions(greedy)
          outdated_info   = "#{cask.token} (#{outdated_versions.join(", ")})"
          current_version = cask.version.to_s
          puts "#{outdated_info} != #{current_version}"
        else
          puts cask.token
        end
