If you say, e.g., `\def\a1{...}', then you must always
put `1' after `\a', since control sequence names are

followed by the required stuff, so I'm ignoring it.

Thank you for the report. There is a known issue with Polyglossia version 1.66 that has been fixed with the release of v2.0 over the weekend. If you’re not using version 2, can you please update and try again?
