Hi, is

Validated.mapN(Semigroup.nonEmptyList(), ...)

gone in 0.12 snapshot ?

[simon.vergauwen]

Yes 😅

We changed it to zip, but a added bonus is you don't need to specify Semigroup.nonEmptyList() for ValidatedNel anymore.

Some context:
Replace mapN with zip

must follow the PRs more closely 😄

Hehe 😅 This is one of the last big changes expected here. mapN didn't feel right since we have zip already in the Kotlin Std already, and we also had it for arity-2 in Arrow. So there was actually duplicated behavior between mapN(v1: Validated<E, A>, v2, Validated<E, B>, f: (A, B) -> C) and Validated<E, A>.zip(b: Validated<E, B>). Since we want to stay close to the idiomatic patterns that Kotlin and the Kotlin Std uses we preferred zip. It's also a popular name for this signature in FP so works out perfectly 😄

And always feel free to ask any questions in this channel. I'm always more than happy to help. I'm also working on a migration guide from 0.11.0 to 0.12.0/0.13.0 😉
