Using exceptions in C++ desktop and server applications overall made sense to me.
As I expanded my usage of C++ into other domains, specifically embedded domains, I began to experience more compelling reasons not to use exceptions first-hand…
At a library level, couldn’t you have an opaque sum type where the only thing you can do with it is call a match method that requires a function pointer for each possible variant of the sum type? It’d be pretty cursed to use but at least it wouldn’t require compiler plugins.
I’d bet five bucks some desperate Haskeller or Rustacean has implemented exactly that. You could also probably use nested functions for GCC C or lambdas in C++ to move everything inline?
