Right. And explaining how to do that, you wouldn't say "pick up the 
items one at a time and if you've already done one with that country, 
skip it", you'd say "pick up one from each country and with it...", 
and if someone asked "okay which one" you'd say "it doesn't matter 
but if you really need me to say, the first one will do".

Thus the declarative approach also allows the implementor to optimize 
where convenient, rather than fussing over details that don't really 
matter to the solution.
