Is there an extension function on Collection that accepts a MutableList and simply adds all its own items to it (i.e. like addAll() in reverse). At the moment I have to do this:

.also {
    targetList.addAll(it)
}

Maybe something like this?

val mutableList = mutableListOf(1, 2)
listOf(3, 4).mapTo(mutableList) { it }

Actually you can write:

val mutableList = mutableListOf(1, 2)
listOf(3, 4).toCollection(mutableList)

Perfect, thanks!
