  There is a similar situation in Italy, with a different geographical
distribution, of course.  Come to think of it, it would be interesting
to compile a map of Europe with the languages that have an ISO 639-3
code, and compare it with the political map.

  Which makes it all the more interesting that OpenType has a language
code for Alsatian (ALS), but none of the other parts covered by gsw.
Harfbuzz maps it to gsw-FR in BCP 47, which I think is sensible.
