Great code-snippet! But maybe align the int value to the actual code? (https://en.wikipedia.org/wiki/List_of_ISO_3166_country_codes)
e.g DK = 208

@pug-pelle-p

I was looking for the same thing and came across this snippet a few days ago. Since I couldn't find a snippet with the enum I wanted, I've decided to write a (very) small tool to generate country-related enumerations based on data from GeoNames.org. You can use it to generate nums with the ISO3166 codes if you would like.
