Might there be a standard lib function that let's me mix two lists?

listOf("a", "b", "c") + listOf("d", "e") = listOf("a", "d", "b", "e", c")

Aye, use this: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/union.html However, it returns

Set

, so you may lose similar elements

fun <T> merge(a: List<T>, b: List<T>): List<T> { var merged =  a.zip(b).flatMap { it.toList() }; return merged + a.drop(merged.size / 2) + b.drop(merged.size / 2) }
