The behavior of a program is a deterministic function of its source
code, right? So if the source code (*all* of it -- everything that

compiled code from previous runs would always yield a correct result.
Am I still on track so far?

Uh-oh, I think I may have already gone off track here in the first
paragraph. What if you use information from the runtime *inputs* --
not imported code but inputted data -- to change how you compile the
code? Then even if *all* of the source code is exactly the same,
re-using the compiled code from the previous run may generate
incorrect results. Is that right?

class A(object):
    if time.time() % 2 == 0:
        def f(self):
            return 1
    else:
        def f(self):
            return 2

Solving the problem of persisting source code is *seriously* hard, and I agree with Armin, I'm not going to invest any time in it.
