cyclops-react VS lambdaj

I always thought cyclops was interesting because it offers both an Eager and Lazy API.

I've used Vavr in couple of projects, but I like https://github.com/aol/cyclops better, although I did not manage to use it in any real project seriously. Mostly just played with Cyclops for fine personal stuff.

yeah, but for example if you use akka in scala you're not only using a "pattern", you add some meaningful functionality (concurrency) and as a by-product you need to use the akka way of doing things. what op proposes on the other hand is some kind of functional syntactic sugar. I accept things like lombok in java because they cut a lot of boilerplate, but in this case my worry is that you end up using more boilerplate or writing some kind of kotlin dialect. plus headaches and probably bugs which come with forcing a non-native library everywhere. I was using this https://github.com/mariofusco/lambdaj in java, which makes it look much cooler and concise, but it ended up having unexpected behavior. also lombok is not problem free. I might understand using such kind of libraries in java, because the language is a dinosaur. but kotlin is modern enough that you don't want to add stuff you don't necessarily need.
