It´´s a very iteresting concept.

The Workflow Monad transformer [1], in Control.Workflow perform logging and recovery of application istate from the log created. It has no implementation of roll-back or limited recovery upto a point, but this is easy to implement.

Is Control.Workflow similar with acid-state with respect to the way you recovery the current state?

It also has many inspection and synchronization primitives. It has been used also for translating the log of a program and recovering the state in another machine. The log can be pretty-printed for debugging.

Can you "somehow" recover impure (IO) computations?
