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: e2mmap.rb
    path of file: ./repos/artichoke/artichoke-backend/src/extn/stdlib/vendor/gen
    
    the code of the file until where you have to start completion: # frozen_string_literal: true
#
#--
#   e2mmap.rb - for Ruby 1.1
#       $Release Versio
    
  def E2MM.Raise(klass = E2MM, err = nil, *rest)
    if form = e2mm_message(klass, err)
      b = $@.nil? ? caller(1) : $@
      b.shift if b[0] =~ /^#{Regexp.quote(__FILE__)}:/
      raise err, sprintf(form, *rest), b
    else
      E2MM.Fail E2MM, ErrNotRegisteredException, err.inspect
    end
