I prefer not to. I think it would be more productive as a private thought experiment: what would you expect a Smalltalk hacker curse about if you forced them to use Common Lisp? a Haskell hacker? a Rust hacker? I think they would miss some really valuable things, and that you could easily miss the value of those things if you took them out of their original context (e.g. considering only whether Lisp would be improved by adopting those specific features.)
