Specs

collect_tagged([OkThen.Result.tagged()], atom()) :: {atom(), [any()]}

Collects an Enum of results into a single result. If all results were tagged with the specified tag, then a result will be returned tagged with tag, whose value is a list of the wrapped values from each element in the list. Otherwise, the result whose tag didn't match tag is returned.
