Deprecated

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 Option DSL or explicit flatmap

Replace with

import arrow.core.None
import arrow.core.Some

flatMap { it.fold({ None }, { a -> Some(a) }) }
