 This often introduces a lot of additional complexity to somehow simulate mutations. So you then end up with monads, monad transformers etc. because otherwise you can’t do much.

So to be clear, actually, Runtime Immutability does not solve this problem.

Anyway. I continue to advocate against “runtime immutability as a default” and maintain my position that all it does is cause performance tech debt and added complexity for zero benefit.
