Would love a way of extending an existing struct as a new type but it not
being related to the struct it extends.
Sort of like a mixin but for structs, so I could have:
struct Object {
let identifier: String
}
struct User: Object {
}
struct Tree: Object {
}
The last two structs get the identifier property "mixed" in but are unique
types :)
