There are solutions to it. For example in Scala I’ve had to use Class tags a couple of times before and they were ergonomic and functioned well

For sure, this has been something I learned from working in Scala that has made my code in other projects much more readable and easier to reason about. For performance reasons I may need to use mutables, but often I can keep it in the context of the function and just encapsulate it.

Iam curious what features do you find missing in rust that the scala ecosystem has? Is it FP specific systems like cats? I know I’ve already seen what seemed like a decent actor system
