That one would probably be somewhat risky actually, that message is the "repr" of the quit object/function, displaying results at the repl invokes repr… but so does printing most containers, so e.g. `vars(__builtins__)` (to get a quick list of the builtins) would also quit the repl, which would be undesirable.
