Request: plural or singular with value

[braco]

I thought this existed in the package, but don't see it. Something like this:

// if value is 1, return singular("word")
// else return plural("word")
quantity("word", value);

There is no proper name that is suitable for the API. So, I have decided to not do this. It is simple enough that people can implement it easily.
