wish: Key by province name as well as province code

[markstos]

I'd like to look up province codes based on the province name.

To avoid making the data structure extra-huge, you might be able to use self-references to avoid making a a second copy of most of the structures. I have not tried this approach, and am not totally sure it's much of win in space savings, but there's a link on self-references in JSON if it's of interest:
