I agree. The important thing for the other cases is to be pragmatic and use the escape hatches. Use a Mutex even though it’s not necessary and accept the runtime cost, or use an unsafe pointer, but get the job done. I’ve seen the phenomenon in both Haskell and Rust now where people would introduce way to much complexity for a relatively simple problem to conform to some sort of ideology.
