Scala shorthand for ending a stream?
scala
Solution
The natural choice, `Stream(lastValue)`, doesn't work in general because `apply` is not lazy, but you can use it when you don't care that you've already assigned the value.
You could possibly use `Stream.fill(1)(lastValue)` when you want the value lazily computed, but it's not exactly obvious why one would use this construct (e.g. it makes one wonder if maybe you would want a number other than 1).
I would favor
lastValue #:: Stream.empty
personally.
Problem
In practicing with Streams I'm discovering a common pattern of ending a stream like this: ``` Stream.cons(lastValue, Stream.empty) ``` This seems like it would be such a common pattern that there is probably a shorthand. Maybe like this? ``` Stream.finish(lastValue) // Not actual Scala code ``` Is such a function built into Scala?
