errors = [IOError, ZeroDivisionError, ArgumentError]

errors.each do |klass|
  begin
    puts "raising #{klass.name}"
    raise klass
  rescue => e
    case e
    when IOError
      puts "it's IOError!"
    when ZeroDivisionError
      puts "it's ZeroDivisionError"
    else
      puts "other error: #{e.class.name}"
    end
  end
end
