I adding LensExtractor.toEither() per example in your docs and then making doing more fine-grained validation but this seems to have broken error handling elsewhere (I guess I need to handle Eithers everywhere then). I wonder if you could point me to those other options as I am pretty new to Kotlin and Http4k.
