Multiple variable let in Kotlin

Question

Is there any way to chain multiple lets for multiple nullable variables in kotlin?

fun example(first: String?, second: String?) {
    first?.let {
        se

For any amount of values to be checked you can use this:

    fun checkNulls(vararg elements: Any?, block: (Array<*>) -> Unit) {
        elements.forEach { if (it == null) return }
        block(elements.requireNoNulls())
    }

And it will be used like this:

    val dada: String? = null
    val dede = "1"

    checkNulls(dada, dede) { strings ->

    }

the elements sent to the block are using the wildcard, you need to check the types if you want to access the values, if you need to use just one type you could mutate this to generics
