Skeptical but curious about sealed classes. Anyone got actual numbers or just vibes

Fair point, I hadn't thought about it that way.

My experience with sealed classes has been mostly positive, but I wouldn't bet the farm on them yet.

Cost matters here. Sealed classes only make sense if the numbers work out at scale.

not convinced about sealed classes tbh. I've seen this hype cycle before and it usually fizzles
