A modern programming language that makes developers happier.

I have a database DAO from which I want to return a `Sequence`. However, I also want to close the db cursor when the sequence has finished consuming. Is this a valid approach?
```
suspend fun findSomethings(...): Sequence&lt;Something&gt; {
  val cursor = ...
  return sequence {
    cursor.use {
      yieldAll(cursor.iterator())
    }
  }
}
```

I would not use that approach. Mainly because if the user of the returned `Sequence` does not fully iterate through it, your cursor will not be closed.

Also, since there is no way to "close" an `Iterable` or `Sequence`, you shouldn't tie the lifetime of a resource to one.

So I would suggest returning a `List&lt;Something&gt;` or (depending on your use case) maybe a `ReceiveChannel` since that can be "close"d.
