Yes, but instances of the old version will remain instances of the old
version, which will not go away until all its instances and other
references go away. So reload is deceptive, which is why it was
semi-hidden away in 3.x in the inspect module.
>>> class C: pass
>>> c = C()
>>> class C: pass # simulate reload
>>> c2 = C()

Restart from the beginning.
