Returns this sequence as a Sequence.
Creates a sequence that returns all elements from this iterator. The sequence is constrained to be iterated only once.

fun main() {
//sampleStart
val array = arrayOf(1, 2, 3)
// create a sequence with a function, returning an iterator
val sequence1 = Sequence { array.iterator() }

// create a sequence from an existing iterator
// can be iterated only once
val sequence2 = array.iterator().asSequence()
assertPrints(sequence2.joinToString(), "1, 2, 3")
// sequence2.drop(1).joinToString() // <- iterating sequence second time will fail
