1//! Every [`Feature`], and each one's name: what the capability matrix (`isoloom matrix`) lists and
2//! names a refusal by. Both come from one list, so a feature added to the enum fails to build
3//! here until it is named: [`Feature::id`]'s `match` covers every one, and [`Feature::ALL`] is
4//! the same list.
