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: backup_path.rb
    path of file: ./repos/imap-backup/lib/imap/backup/setup
    
    the code of the file until where you have to start completion: module Imap; end

module Imap::Backup
  class Setup; end

  # Requests an updated backup path from the user
  class Setup::BackupPath
    # @param account [
    
    def path_modification_validator(path)
      same = config.accounts.find do |a|
        a.username != account.username && a.local_path == path
      end
      if same
        Kernel.puts "The path '#{path}' is used to backup " \
                    "the account '#{same.username}'"
        false
      else
        true
      end
