There’s a sense in which it’s pedantically correct - ‘exit’ (and ‘help’) are not Python keywords outside of the REPL, so a beginner might try to use it in a script (maybe like sys.exit()?) and be confused. But I think the convenience is worth it.
It's fun because `exit` alone in the REPL will return an object, and you can get the `exit.eof`, where is the message of what the keyword shortcut to call exit is, and it changes depending on the OS.
