sealed abstract class Call[A] extends Eval[A]

Call is a type of Eval[A] that is used to defer computations which produce Eval[A].
Call is a type of Eval[A] that is used to defer computations which produce Eval[A].
Users should not instantiate Call instances themselves. Instead, they will be automatically created when needed.
sealed abstract class Compute[A] extends Eval[A]

Compute is a type of Eval[A] that is used to chain computations involving .map and .flatMap.
Compute is a type of Eval[A] that is used to chain computations involving .map and .flatMap. Along with Eval#flatMap it implements the trampoline that guarantees stack-safety.
Users should not instantiate Compute instances themselves. Instead, they will be automatically created when needed.
Unlike a traditional trampoline, the internal workings of the trampoline are not exposed. This allows a slightly more efficient implementation of the .get method.

Static Eval instances for some common values.
These can be useful in cases where the same values may be needed many times.

def defer[A](a: ⇒ Eval[A]): Eval[A]

Defer a computation which produces an Eval[A] value.
Defer a computation which produces an Eval[A] value.
This is useful when you want to delay execution of an expression which produces an Eval[A] value. Like .flatMap, it is stack-safe.
