What could you possibly want to do this for so badly that you would
shun all alternatives and even resort to hacking up the runtime at the
C-level to redefine core types in non-standard and unpredictable
ways?! Seriously, please give a good reason for every doing this. I
can't imagine there is any way it would justify all this in the face
of just looking for an alternative. You aren't trying to use python,
at this point, you are trying to fork it.
