This API is niche and will be removed in the future. If this method is crucial for you, please let us know on the Arrow Github. Thanks! https://github.com/arrow-kt/arrow/issues Prefer using the Either DSL, or map + mapLeft

Replace with

map(rightOperation).mapLeft(leftOperation)

Map over Left and Right of this Either
