List matching tends to be fairly useful even its very limited form in my lib. Its basically arity match + de-structure. It doesn't nest like full fat pattern matching. I don't see how tuple matching is as useful (over your 'With' fn or my 'Apply') unless it can nest, especially with matches on union types. e.g (Maybe a, b) | (Nothing, b) Basically I feel like such a thing is going to be very hard in C# to achieve with any sort of usable api. I personally took the route of the api being more important than whether any sort of decent abstraction is actually there behind the scenes - I didn't mind writing 100's lines of boilerplate to get the result and behaviour I wanted. Its great to see more functional support for C# from the community and I look forward to using your lib in the future!
