repr is generally assumed to be side effect free and cheap to run, so things like debuggers tend to show repr of things in scope, including possibly exit
also then it behaves differently between repl and script, since repr never gets run. to do it properly it has to be a new repl keyword I imagine, but I still don't know if I'm sold on the idea
I think if they were planning this at all, we'd see linux support for maui. currently their linux use has been very focused on only for devs and servers
