also we can make some eyes bleed with

fun <T1 : Any, T2 : Any, T3 : Any, T4: Any, T5: Any, R: Any> safeLet(p1: T1?, p2: T2?, p3: T3, p4: T4, p5:T5, block: (T1, T2, T3, T4, T5) -> R?): R? {
    return if (p1 != null && p2 != null && p3 != null && p4 != null && p5 != null) block(p1, p2, p3, p4, p5) else null
}
