Re: [csswg-drafts] [css-values-5] Introduce nth-item() (#11103)

Would negative indices count from the end of the list? What would index `0` return then?

I’ve expressed a preference for a unified _select by index_ function before. I’m still in favor of it, but overall it’s just syntax details. 

~~~~ ebnf
select( random | <integer> , [ <declaration-value>? ]# )
~~~~

If this also supported _select by key_, we’d basically have a switch construct without fallthrough behavior. 

~~~~ ebnf
select( random | <integer> | <string> , [ [<string> :]? <declaration-value>? ]# )
~~~~
