/**
 * Returns an effect whose failure and success have been lifted into an
 * `Either`. The resulting effect cannot fail, because the failure case has
 * been exposed as part of the `Either` success case.
 *
 * This method is useful for recovering from effects that may fail.
 *
 * The error parameter of the returned is `never`, since it is
 * guaranteed the effect does not model failure.
