About that last point: it would not be possible to have both the
`Arrayable` interface and the `arrayable` reserved word because PHP is
case-insensitive for those things (the same way you cannot declare an
`interface Iterable` because of the `iterable` reserved word,
<https://3v4l.org/Fhqar>), so you would need another name (if you want
the alias)
