But it's not just C because the source code includes the python that is
modifying it. After all, for almost any given outcome you desire, you'll
have a choice between implementing it in C, implementing it by enhancing
the python, or some combination of the two. The semantics sure aren't
completely defined by the *.c files any more.

I fear you'll end up constantly tweaking the Python, occasionally needing
to change semantics there, which will break a lot of your existing "C" (not
C because it was written so that the generator would manipulate it in a
desirable way).
