This package contains efficient free categories. There are two presentations:

Free arrows and free Kleisli categories are also included.

Free categories are useful to model state machines in a simple yet type safe manner. For that purpose Kleisli categroies are a very useful target which allows to include monadic computations. This packge contains a useful generalisation of Kliesli categories captured by EffCategory class (effectful categories), and a (free) transformer which lifts a category to an effectful one.
