Whats the opinion of using run with the elvis operator as a sort of guard statement like in iOS?
I’ve wanted a way to do a sort of side effect like logging when using ?: to exit a function
Something like

fun takesNullables(val string: String?) {
    val notNull = string ?: run {
        println("arg was null")
        return
    }
}

// Or a more complicated usage 
fun gaurdTest(val nums: List<Int>, val person: Person) {
    val firstEvent = nums.firstOrNull { it % 2 == 0 } ?: run {
        println("no evens in $nums")
        return
    }
    // Or 
    val streetName = person?.address?.streeName ?: run {
        println("street name not found")
        return
    }
}

Seems like something I would do.

Yeah seems fine to me as well 🤷🏻‍♂️

You can directly go for return println("...") in your case. If things get more complex I would be temped to extract everything in run into a private method
