Can I map a list into two separate lists based on the fields?
```val list = listOf&lt;Pair&lt;Int, Int&gt;&gt;()
val (firstList, secondList) = ?? //how to do the mapping on the list here```

It's not exactly what I look up, let me elaborate in a real example:
```data class User(id, name)
val list = List&lt;User&gt;()
val (ids, names) = list.? // I need to map the ids into the first list and the names into the second list```

<https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/unzip.html>

e.g.
```val (ids, names) = list.map { it.id to it.name }.unzip()```

Thanks man, that's what I'm looking for exactly!
