'Either' does not cover the case where the outcome was successful but generated warnings. I already looked into it and also at 'Try' from which I got inspired. Thanks for pointing it out anyway!

I deal with a lot of CSV files from many different sources and they are often malformed. HOwever, I just have success/failure. Maybe you should make SuccessWithWarnings a subclass of success, or getting rid of it altogether making the warnings optional. I was thinking of making this cleaning/conforming library open source if you're interested.

All I was able to find was the flatMap/Some/None technique + logging. I'm facing this problem because I have a processing algorithm that extracts more than one value from each record, but can fail in extracting one of those multiple values, and I want to keep track of them. Logging is not feasible because this "warning" happens so frequently that the logs would become overwhelming and impossibile to read. Since I have 3 different possible outcomes from my processing I modeled it with this class hierarchy: [cid:935118B9-A7BA-4D67-815A-B861FA866DAF] That holds result and/or warnings. Since Result implements Traversable it can be used in a flatMap, discarding all warnings and failure results, in the other hand, if we want to keep track of warnings, we can elaborate them and output them if we need.
