+Plurals expect a variable `count` that implement `Fn() -> N + Clone + 'static` where `N` implement `Into<icu_plurals::PluralsOperands>` ([`PluralsOperands`](https://docs.rs/icu/latest/icu/plurals/struct.PluralOperands.html)). Integers and unsigned primitives implements it, along with `FixedDecimal`.
