final case class Cons[A](a: A, tail: Eval[Streaming[A]]) extends Streaming[A] with Product with Serializable
final case class Empty[A]() extends Streaming[A] with Product with Serializable

Concrete Streaming[A] types:
Concrete Streaming[A] types:
- Empty(): an empty stream.
- Cons(a, tail): a non-empty stream containing (at least) a.
- Wait(tail): a deferred stream.
Cons represents a lazy, possibly infinite stream of values. Eval[_] is used to represent possible laziness (via now, later, and always). The head of Cons is eager -- a lazy head can be represented using Wait(always(...)) or Wait(Later(...)).

def cons[A](a: A, ls: Eval[Streaming[A]]): Streaming[A]

Prepend a value to an Eval[Streaming[A]].
def cons[A](a: A, s: Streaming[A]): Streaming[A]

Prepend a value to a stream.
def continually[A](a: A): Streaming[A]

Continually return a constant value.
def defer[A](s: ⇒ Streaming[A]): Streaming[A]

Defer stream creation.
Defer stream creation.
Given an expression which creates a stream, this method defers that creation, allowing the head (if any) to be lazy.

def from(n: Int): Streaming[Int]

Stream of integers starting at n.
def fromIterable[A](as: Iterable[A]): Streaming[A]

Create a stream from an iterable.
Create a stream from an iterable.
The stream will be eagerly evaluated.
def fromIteratorUnsafe[A](it: Iterator[A]): Streaming[A]

Create a stream from an iterator.
Create a stream from an iterator.
The stream will be created lazily, to support potentially large (or infinite) iterators. Iterators passed to this method should not be used elsewhere -- doing so will result in problems.
The use case for this method is code like .fromIterable, which creates an iterator for the express purpose of calling this method.
def fromList[A](as: List[A]): Streaming[A]

Create a stream from a list.
Create a stream from a list.
The stream will be eagerly evaluated.
def fromVector[A](as: Vector[A]): Streaming[A]

Create a stream from a vector.
Create a stream from a vector.
The stream will be eagerly evaluated.

This method only differs from continually in that the thunk may not be pure. Thus, repeated traversals may produce different results.

Produce a stream given an "unfolding" function.
None represents an empty stream. Some(a) reprsents an initial element, and we can compute the tail (if any) via f(a).
