Question: I have a method that should convert a list to an `Option` of an object, or `None` if the list is empty.

```
def listToOption(myList: List[Foo]): Option[Bar] = {
  if(myList.nonEmpty) Some(Bar(myList))
  else None
}

case class Bar(fooList: List[Foo]) {}

```

For some reason, my solution feels rather inelegant, and not the Scala way. It seems I should be able to use a method on `List` to do this sort of thing, but I can't wrap my head around it.

Is there a more Scala-like way to do this?

Answer: 
```
myList.headOption.map(_ => Bar(myList))

```
```
import scalaz._; import Scalaz._
myList.toNel.map(Bar)

```

`toNel` - is "to non-empty list" here, it returns `Option[NonEmptyList]` for safety:

```
scala> case class Bar(a: NonEmptyList[Int])
defined class Bar

scala> List(1,2,3).toNel.map(Bar)
res64: Option[Bar] = Some(Bar(NonEmptyList(1, 2, 3)))

scala> List[Int]().toNel.map(Bar)
res65: Option[Bar] = None

```
