How would you assign languages to ZIDs?
Currently the idea is to reserve the four digit ZIDs for languages.
I would like to start with the languages that are user interface languages
for MediaWiki (but there's enough space to extend this considerably later).
But how to turn them into numbers?
The best way I can come up with is to take the language codes, sort them
alphabetically, and take that for the first set, and then, when more come
in, add them chronologically. Let's have that as the strawman proposal, but
maybe someone can come up with a smarter idea?
