Here is another option.

Look at the InteractiveConsole class.  When you make a change, run the
command:

>>> changed

Your subclass of InteractiveConsole catches it and does not send it to
the compiler.  Instead, it closes and reruns the entire session so
far.  Or, just the imports and definitions, which you have to detect
by hand.  This is probably the hard way.
