FlatMap()

FlatMap is a type of Eval 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 FlatMap 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 .value method.
