Hi everyone! I'm trying to do something like this with only Arrow Core

Option.fromNullable(nullableValue).mapNotNull(::f1).flatMap(::f2)

where f1 is suspend (String) -> String? and f2 is suspend (String) -> Option(Whatever), is this supported?

Hey @pepe,

This is support but Kotlin doesn't accept lambda references for inline fun even though it supports it.

If you write the equivalent code below it'll work.

Option.fromNullable(nullableValue).mapNotNull { f1(it) }.flatMap { f2(it) }

ah, I see, thanks. As a follow-up question, do you know if there's a KEEP or any intentions to support this in the future?

[simon.vergauwen]

Don't think there is a KEEP actually but I've discussed it before in language proposals.

They've improved/solved similar issues in the passed.
