Kotlin: Check for Null and Assign?

var something: Something? = null
val notNull: Something = ...

...

fun getSomething() {
    something = something ?: notNull
    return something
}

Is there in Kotlin any way to do both something = something ?: notNull; return something at the same time?

Or.. even better, is there a way to do it with generics in an inline function?

fun getSomething(): Something {
    return something ?: notNull.also { something = it }
}
// or 
fun getSomething(): Something = something ?: notNull.also { something = it }
