basically, what I'd like to do is:

val klass=elt::klass
klass.memberProperties.map { prop -> /* something here */ },joinToString()

- I just can't figure out what belongs in

something here

such that the property is extracted from

elt

prop.get(elt)

That gives me a compiler error:

Error:(80, 53) Kotlin: Out-projected type 'KProperty1<out Any, Any?>' prohibits the use of 'public abstract fun get(receiver: T): R defined in kotlin.reflect.KProperty1'

Yes, this is something the compiler can't prove is correct. You need an unchecked cast.

(prop as KProperty1<Any, Any?>).get(elt)

trying. That compiles, at least!

Okay, there are some other issues here, will chase them. Thank you VERY much!
