No, the python language doesn't really support execution resumption
after an exception. I imagine one could hack up something very nasty
that would involve an exec-like function that takes the existing stack
and restarts it with modified pointers to new code, but it's not
anything that I've seen done, nor that I plan on writing anytime soon
