This API is considered redundant. If this method is crucial for you, please let us know on the Arrow Github. Thanks! https://github.com/arrow-kt/arrow/issues Prefer zipOrAccumulate

Replace with

Either.zipOrAccumulate({ a, bb -> SGA.run { a.combine(bb) }  }, this, b) { a, bb -> SGB.run { a.combine(bb) } }
