yieldAll

abstract suspend fun yieldAll(iterator: Iterator<T>)(source)

Yields all values from the iterator to the Iterator being built and suspends until all these values are iterated and the next one is requested.

The sequence of values returned by the given iterator can be potentially infinite.

   //sampleStart 
   val sequence = sequence {
    val start = 0
    // yielding a single value
    yield(start)
    // yielding an iterable
    yieldAll(1..5 step 2)
    // yielding an infinite sequence
    yieldAll(generateSequence(8) { it * 3 })
}

println(sequence.take(7).toList()) // [0, 1, 3, 5, 8, 24, 72] 
   //sampleEnd
}
