maybe this has been discussed already but for the following case:

Copy code

fun foo(items: List<SomeInterface>?) {
    when (items?.firstOrNull()) {
        is Bar -> doBar(items)
        is Buzz -> doBuzz(items)
    }
}

why can't

items

be smart-casted to

List<SomeInterface>

doBar

and

doBuzz
