Minor style point – this should be a failable init on Int rather than a
computed property on Character
i.e. Int.init?(_: Character), matching Int.init?(_: String, radix: Int = 10),
only it doesn’t need the radix arg cos it’s only a single character.
If implemented inside the std lib, it can still access character’s internals,
which is a reasonable thing to do for something so performance-sensitive.
