Hi :wave: , another migration question from `0.11....

Hi 👋 , another migration question from 0.11.0 to 0.13.1 . How would I write this function now:

suspend fun buildPerson(): Either<DomainError, Person> {
    val name: Either<DomainError, Name> = getName()
    val address: Either<DomainError, Address> = getAddress()
    val dob: Either<DomainError, Date> = getDOB()
    return Either.applicative<DomainError>().tupledN(name, address, dob).map {
        Person(name = it.a, address = it.b, dob = it.c)
    }
}

Follow-up: Can I accomplish this in parallel (assuming get* function are suspending )?

Hi @Josh, It may look like this:

either.parzip.kt

thank you!

Without parallelisation it would look like the following:

fun buildPerson(): Either<DomainError, Person> =
  getName().zip(
    getAddress(),
    getDOB()) { name, address, dob ->
      Person(name, address, dob)
  }

Or you could user either { } of course also.
