A modern programming language that makes developers happier.

kotlinlang

I know that is odd code, its from like 1940 Kotlin.  (the year).  When modernized to this, no warning:

It is `toTypedArray()` causing it on many things.   And I know this is odd code because when modernized to the following, no warning:

```
    private val people = listOf(
            Person(1, "Frank", 30),
            Person(2, "Domingo", 19),
            Person(3, "Mariana", 22),
            Person(4, "Lucia", 31)
    ).associateByTo(HashMap()) { it.id }
```

but this makes the warning:

```
val x = listOf(1,2,3).map { it to it * 4 }.toTypedArray()
```
