Support single-case discriminated union

Could be easily added, why not send a PR. (Note I'm not a maintainer and have fixed similar things in the lib)

I've actually hacked together a fix locally based on the source code of this library. I might need to do some refactoring, but I could try to make a PR out of it when I get the time.

@drhumlen Project is still maintained and is open to suggestion/PR.
As for this specific suggestion, I can see how this could be useful in certain cases, and perhaps less desired in other cases. I would recommend making this optional, and also adding unit tests to make sure that it's backward compatible. Looking forward to reviewing your PR!

Or is FSharpLu.Json abandoned? What should I use instead? Newtonsoft is 100% useless – it doesn't even encode Option correctly. I've actually been struggling really hard for the past 6 months to find a json library for F# that works and has users. Does F# even have other users when you can't even find a library for json? Scala , by comparison, has at least 5 that are all really good.
