 When you run the above method, you will notice that it returns `None` when any of the input elements is negative. Moreover, thanks to `boundary`/`break`, you can see from the console output that it stops iterating after encountering the first negative element.
 
-`break` can jump out of the `boundary` in the function deeper on the stack. To make it safe, only functions with a matching `Label` in their using clauses can break. This can be used to create isolated parts of an application with streamlined error handling.
-
-Library authors can abstract over `break` and `Label`, creating a nice API for error handling or dealing with uncertain data. We can define the following micro-library as a simplified example:
-
-```Scala
-import util.boundary, boundary.{ Label, break }
-
-type Uncertain[T] = Label[Left[String, Nothing]] ?=> T
-
-def fail(error: String): Uncertain[Nothing] = break(Left(error))
-```
-
-Then it can be used in the following way to create a fragment of a larger application with isolated error handling:
-
-```Scala
-def getUser(id: String): Uncertain[User] =
-  val user = findUser(id)
-  if verifyUser(user) then user else fail("Incorrect user")
-
-def getAddress(user: User): Uncertain[Address] =
-  findAddress(user) match
-    case Some(address) if verifyAddress(address) => address
-    case Some(_) => fail("Incorrect address")
-    case None => fail("Missing address")
-
-def getShippingData(id: String): Either[String, (User, Address)] =
-  boundary:
-    val user = getUser(id)
-    val address = getAddress(user)
-    Right((user, address))
