Hi Chris,
This is great. Thanks for spending time on this! I am in favor of `case #unknown` to only match unknown cases.
1) Would #uknown be available to RawRepresentable structs?
I haven’t considered this, so I’m not sure how that would work. I had assumed that this would be an enum specific concept.
What do you have in mind? If your raw representation is itself an enum, then of course this would work.
2) How is the #uknown pattern accomplished? Are you suggesting to capture all the compile time known cases so you can do a diff during
runtime? (Sorry this is not obvious to me)
The internals of the compiler would handle this, it is difficult to explain unless you know the bowels of silgen and irgen :-)
