An effectful function from A to B; when executed, it may update any number of Refs atomically. (It may also create new Refs.)
These functions are composable (see below), and composition preserves their atomicity. That is, all affected Refs will be updated atomically.
A Rxn forms an Arrow (more specifically, an ArrowChoice). It also forms a Monad in B; however, consider using the arrow combinators (when possible) instead of flatMap (since a static combination of Rxns may be more performant).
The relation between Rxn and Axn is approximately Rxn[A, B] ≡ (A => Axn[B]); or, alternatively Axn[A] ≡ Rxn[Any, A].
