You have

typealias Stringish = String
var x: Stringish
func examp() {
    x = "yo"
    print(x)
}

and you have a zillion Stringish in your code base. You suddenly realize you need something more like

struct StringBonus {
    var value: String
    var version: Int
}
typealias Stringish = StringBonus

which is fine but you have to replace “x” everywhere with “x.value”, as it were.

x.value = "yo"
print(x.value)
etc etc etc
var x: Stringish = tedious default value
etc etc etc

It would be incredible if you could still refer to x normally,

x = 69

but also access the “hidden” fields,

x.version = 2

Can anyone think of a way to make a struct “default” to one of the fields, or indeed a trick approach that achieves the same result.

I guess the amazing @resultBuilder would be impressive but I can’t see a way to have a free-form resultBuilder inline (where the “x” is).

Maybe someone has a way.
