I think there is a very similar library in Haskell called project m36. Here's its github page on transactions: https://github.com/agentm/project-m36/blob/master/docs/trans...

In Related: Pure Ruby Relational Algebra EngineIf you are referring to object-oriented polymorphism, "Out of the Tarpit" comments directly on this AT http://shaffner.us/cs/papers/tarpit.pdf page 12, the conclusion being that OO suffers from unnecessary state complexity.
In addition, the glut of ORMs demonstrate the various approaches to solving the impedance mismatch between the relational algebra and object-oriented architecture with no clear winning strategy.
Instead, the proposal from the "Out of the Tarpit" paper is "functional relational programming" which fuses relational algebra operations and declarative functional programming.
I invite you to take a look at how Project:M36 handles these requirements at https://github.com/agentm/project-m36/blob/master/docs/reach...
