Maybe it could prompt the user that the interpreter will need to be
restarted for the changes to take effect. IDLE runs the interactive
interpreter in a separate process so it could restart the subprocess
without closing the GUI (after prompting the user with a restart/continue

I'm not sure if the standard interpreter would be able to relaunch itself
but it could at least exit and tell the user to restart (after a yes/no
question in the terminal). The command could also be limited to the when
the interpreter is in interactive mode.

How it works in the terminal is less important to me than how it works in
IDLE though; being able to teach how to use Python through IDLE (deferring
discussion of terminals etc) is useful for introductory programming classes.
