You can pass the 'classic' option if you want the function to behave the old way, that is calling slower `utils.decodexml` to parse the XML file which may fail sometimes with elaborate tag attributes. - Many functions in the `ints`, `long` and `mapm` packages that process one or more values returned `true` when given no argument at all. In this case, the functions now issue an error.
