I'm working with a bunch of traditional functions - I can catch to get a Either<Throwable, *> from a function that may throw. I'm looking for the reverse. I want to throw if right. Should I just create an extension function?

Yes, we purposely do not expose such functions from Arrow-Core.

We might consider exposing it from Arrow Fx Coroutines like we do for IO<Either<Throwable, A>> => IO<A>. Since Either<Throwable, A> => (suspend () -> A) is a pure transformation.

Does that mean throwing an exception in case you get the right value? (Aka not an left side of the either which is the exception?)

Sorry, mistyped. I meant left. And yes, makes sense Simon.
