Kotlin - The Good, the Bad and the Ugly

There's a portion in it where Streams are discussed; short answer is
  • Kotlin has Streams
  • All collection classes in Kotlin already supports the one-time_iterator behavior of java.util.stream.Stream instance
  • Kotlin doesn't need the initial conversion (collection to stream) and the final conversion (stream back to a collection)
  • BUT remember that Java streams are lazily evaluated while Kotlin streams are eagerly evaluated unless you convert to a Sequence
