fun foo(bar: List<Int>): Int {
    check(bar.isNotEmpty())

    return bar.max()!! / 2
}

How would you deal with max returning a nullable value, other than !!? Does it bother you?

If foo is fine to thrown exception (as I suspect based on the check), you can do something like:

fun foo(bar: List<Int>): Int =
        bar
                .max()
                ?.let { it / 2 }
                ?: throw Exception("foo failed")

You can use error("foo failed") instead of throw Exception

I have written .maxOrThrow() extension function
