It seemed like the core team wanted general solutions that can be implemented for all keywords, and a general solution for declaring enum cases without backticks is probably not possible, I think?

I still don’t see why not. What could possibly come after the ‘case’ in an enum declaration other than the name of the enum case itself?

To my knowledge, the only modifier of an enum case is the “indirect” modifier, but that always comes *before* the “case” keyword, so there’s no ambiguity there.
