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: exception_handler.rb
    path of file: ./repos/localeapp/lib/localeapp
    
    the code of the file until where you have to start completion: module Localeapp
  class ExceptionHandler
    def self.call(exception, locale, key_or_keys, options)
      keys = Array(key_or_keys).map 
    
    def self.call(exception, locale, key_or_keys, options)
      keys = Array(key_or_keys).map { |key| ERB::Util.html_escape(key.to_s) }
      scoped_keys = keys.map { |key| [options[:scope], key].compact.join(".") }
      Localeapp.log(exception.message)
      # Which exact exception is set up by our i18n shims
      if exception.is_a? Localeapp::I18nMissingTranslationException
        Localeapp.log("Detected missing translation for key(s) #{scoped_keys.inspect}")

        keys.each do |key|
          Localeapp.missing_translations.add(locale, key, nil, options || {})
        end

        [locale, scoped_keys].join(', ')
      else
        Localeapp.log('Raising exception')
        raise
      end
