@ExperimentalUnsignedTypesinline fun ULongArray.asLongArray(): LongArray(source)

@OptIn(ExperimentalUnsignedTypes::class)
fun main() {
    val uLongs: ULongArray = uLongArrayOf(10uL, 20uL, 30uL)
    val longs: LongArray = uLongs.asLongArray()
    println(longs.joinToString()) // prints: 10, 20, 30
