Stateful

Namespace for convenient versions of Stateful class, specialized by partially applying some or all of its type parameters.

For example: Stateful.FromId.ToId.Free is equivalent of Stateful[[X] =>> X, [X] =>> X, ThisEffect, Any]

This works like type-level "fluent interface", where:

• FromId and FromConst partially apply F[+_] parameter of Stateful class.
• ToId and ToConst partially apply G[+_] parameter of Stateful class.
• Free partially applies Fx parameter of Stateful class.
