Is it possible for me to create a function that would look something like this?

[jeggy]

interface A { val field: Int }
data class B(override val field: Int): A

fun <T: A> myFunction(property: KProperty1<T, Int>? = null) {
    val kProperty = (property ?: A::field) as KProperty1<Any, Int>
    /* Something */
}

fun main() {
    myFunction(B::field)
}

Solved it with a small hack 👌

did you try

fun myFunction(property: KProperty1<out A, Int>)

?

That doesn't work

I tried with <out T, Int> . But that breaks the usage of kProperty.get as now it requires a Nothing object instead of T or A.
