Can one use the either {} monad comprehension also outside suspending context? I want to use it in a non-suspending function, but it seems that arrow.core.continuations.either only has a suspending version of `invoke()`:

public suspend operator fun <E, A> invoke(f: suspend EffectScope<E>.() -> A): Either<E, A> =
    effect(f).toEither()

you can use either.eager {} from non suspend context
