Hello everyone. I maybe need some helps: I need call

In fact I can't achieve that, because looks the default value expression or other representation of the default value is not included in the MetaData

In theory default parameter in function can be some property (which includes calculated or mutable one) : import kotlin.random.Random fun main() { foo(2) foo() foo() bar(2) bar() altNumber = 5 bar() } val someNumber get() = Random.nextInt() fun foo(number: Int = someNumber) = println(number) var altNumber = 4 fun bar(number: Int = altNumber) = println(number) So you kinda can avoid reflection by assigning current default value somewhere. Maybe there are better solutions for that, but that's the first thing that comes to my mind :)
