For the record: don't try this if you have unsaved files open on your
computer, because you will lose them. When I typed these two lines
into the Py3.5 interactive prompt, it completely and totally froze
Windows to the point that nothing would respond and I had to resort to
the old trick of holding the power button down for five seconds to
forcibly shut the computer down.

Fortunately, I made extra certain everything was fully saved before I
opened the Python interpreter, so I'm not TOTALLY dumb. :-P
