is there a function like Either<Throwable, T>.getOrThrow(): T ? i've been using when() to change behavior on Left or Right but it's kinda verbose.

throwing is discouraged, so when/fold is the way to go if you want to do it 😄

[Tom Davis]

gotcha. i don't want to, but that's the controller api 😉

[Alejandro Serrano.Mena]

in those cases you can do theEitherValue.getOrElse { throw it }, which I find quite readable and not so verbose

[CLOVIS]

@Alejandro Serrano.Mena any preference between
either.getOrElse { throw it }
and
either.recover { throw it }
?

To my knowledge, these behave the same?

[Alejandro Serrano.Mena]

I tend to use the first one, mostly out of taste (and it also feels a bit weird to say that "throwing" is recovering from an exception 😅)

also lately I'm trying to use Raise<Error>.f(): A more often than Either<Error, A>, and in that case I just use fold to make a final throw
