final case class Now[A](value: A) extends Leaf[A] with Product with Serializable
Construct an eager Eval[A] instance.
In some sense it is equivalent to using a val.
This type should be used when an A value is already in hand, or when the computation to produce an A value is pure and very fast.

Lazily perform a computation based on an Eval[A], using the function
fto produce an Eval[B] given an A.Lazily perform a computation based on an Eval[A], using the function
fto produce an Eval[B] given an A.This call is stack-safe -- many .flatMap calls may be chained without consumed additional stack during evaluation. It is also written to avoid left-association problems, so that repeated calls to .flatMap will be efficiently applied.
Computation performed in f is always lazy, even when called on an eager (Now) instance.
