 Arrow Fx makes emphasis in guaranteeing users understand when they are performing side effects in their program declaration.
 
-Arrow Fx programs are not restricted to `IO` but in fact polymorphic and would work unmodified in many useful runtimes like the ones we find in popular libraries such as KotlinX Coroutines `Deferred`, Rx2 `Observable`, Reactor framework `Flux` and in general any third party data type that can model sync and async effect suspension.

 If you've come this far and you are not too familiar with FP you may have realized that despite the buzzwords and some FP jargon, you already know how to use Arrow Fx for the most part. That is because Arrow Fx brings the most popular imperative style to effectful programs with few simple primitives for effect control and asynchronous programming.

 Polymorphic programs are more flexible that their concrete counterparts because they can run unmodified in multiple runtimes.
 In the same way `main` is concrete in the previous example to `IO`, we could have used there instead Rx2 Observables, Reactor Flux or any other data type that is able to provide extensions for `Fx` and `UnsafeRun`.
