15.  def observe(sink: Sink[F, O])(implicit F: Concurrent[F]): Stream[F, O]

    Synchronously sends values through sink.

    Synchronously sends values through sink.

    If sink fails, then resulting stream will fail. If sink halts the evaluation will halt too.

    Note that observe will only output full chunks of O that are known to be successfully processed by sink. So if Sink terminates/fail in middle of chunk processing, the chunk will not be available in resulting stream.

    Note that if your sink can be represented by an O => F[Unit], evalTap will provide much greater performance.

    Example:

    1. scala> import cats.effect.{ContextShift, IO}, cats.implicits._
       scala> implicit val cs: ContextShift[IO] = IO.contextShift(scala.concurrent.ExecutionContext.Implicits.global)
       scala> Stream(1, 2, 3).covary[IO].observe(Sink.showLinesStdOut).map(_ + 1).compile.toVector.unsafeRunSync
       res0: Vector[Int] = Vector(2, 3, 4)

16.  def observeAsync(maxQueued: Int)(sink: Sink[F, O])(implicit F: Concurrent[F]): Stream[F, O]

    Send chunks through sink, allowing up to maxQueued pending _chunks_ before blocking s.

17.  def pull: ToPull[F, O]

    Gets a projection of this stream that allows converting it to a Pull in a number of ways.

18.  def repeatPull[O2](using: (ToPull[F, O]) ⇒ Pull[F, O2, Option[Stream[F, O]]]): Stream[F, O2]

    Repeatedly invokes using, running the resultant Pull each time, halting when a pull returns None instead of Some(nextStream).
