Hi, since we are all talking about Effect I would have one question too. Is it possible to compose multiple `Effect`s? For example:

fun test(): Effect<X, Int> = effect {
    1
}

fun test2(num: Int): Effect<X, Int> = effect {
    num + 1
}

(test().flatMap { num -> test2(num) }): Effect<X, Int>

Hey @Pavel,
Yes, the effect block allows for a special DSL.

effect {
  val num = test().bind()
  val num2 = test2(num).bind()
  num + num2
}

It also exposes functionality such as Either#bind, ensureNotNull etc

I noticed Effect is not linked on the Arrow Core homepage overview.

Hi @simon.vergauwen,

thanks for your speedy reply, so bind() should be used to connect `Effect`s. I tried it now and it works 🙂
