expected_error_message = <<-MESSAGE
method `double_optional_argument' has optional positional argument `album2', after optional argument `album1'.
We cannot use this method because there's no way to supply an explicit value for `album2' without knowing the default value for `album1'. It's technically possible to overcome this with S-expression analysis, but a much simpler solution would be to use keyword arguments.
