Well

tailrec

on a function that doesn't actually have any tail recursion is always a mistake, so it deserves a warning. Consider this code though:

Copy code

fun foo(list: List<Int>) {
    list.forEach {
        if(it == 0) return
        println(it)
    }
    println("done")
}

The

return

here isn't wrong, so it shouldn't get a warning. How do you separate them?
