Hi 🙂 Another FP newbie here 😉 And one thing bothers me: what type/container should I use to represent a single value that’s neither optional nor can fail in any way, but I still want to map over it? I know I could use Kotlin’s let, but maybe there’s a proper FP way of doing this?

Edited: Ohhh, I misunderstood your question and Raul already answered you

Original: I'm far from being an expert, but if you use Arrow lib, you can try something like

val potentialNumber: Try<Option<Int>> = Try { Some(1) }
potentialNumber.map { maybeNumber ->
maybeNumber.map { "My number is $it" }
}

Hope that helps 🙂
