# arrow

A good way to put monads to practice in Kotlin is using arrow-effect and the Effect hierarchy to build imperative programs with binding comprehensions and observing how that frees you from the runtime and it allows your programs to run in Kotlin Coroutines Deferred, Rx Observables, Reactor Flux, etc.

I believe that one of the main reasons people are migrating out of Rx2 and into Coroutines it’s because of the async/await syntax and you can do that with Arrow for all data types that provide a Monad<F> instance where F is any of the docens of data types that Arrow supports today: async/await is the same as binding/bind but binding works in ALL monad capable data types.
