Fwiw, OCaml algebraic effects are being implemented: http://kcsrk.info/ocaml/multicore/2015/05/20/effects-multico...

I actually tried to use it very recently in a new project at my workplace, but unfortunately I decided not to. I found some fundamental things were lacking.
I didn't find documentation about how to interact with npm libraries (e.g. how do I use a websockets library in Reason? Do I have to create my own bindings? If so, how?).
There also seemed to be nothing similar to async/await in Reason/Bucklescript yet and I couldn't find out how to use promises.
I'll definitely reevaluate it in the future. I think it is an awesome project with great potential (along with Bucklescript which is awesome too).
