Utility for Filtering Errors by Tags in Effect Typescript

function filterErrors<const P extends ReadonlyArray<string>>(...exceptTags: P) {
  const tagSet = new Set<string>(exceptTags as ReadonlyArray<string>);

  return <A, E extends { _tag: string }, R>(
    effect: Effect.Effect<A, E, R>,
  ): Effect.Effect<A, Extract<E, { _tag: P[number] }> | UnknownException, R> =>
    effect.pipe(
      Effect.mapError((error) =>
        tagSet.has(error._tag)
          ? (error as Extract<E, { _tag: P[number] }>)
          : new UnknownException(error)
      ),
    );
}

someEffect.pipe(filterErrors("AnErrorTagToPassThrough"))
