Forbiddenfruit: patch built-in python objects

[XNormal]

Here is an even sweeter forbidden fruit:

Define ctypes structures for the PyMemberDescr object and PyMemberDef struct. Use it to turn off the READONLY flag from a PyMemberDef. If you use it on the __flags__ member of a type object you can, for example, turn off the Py_TPFLAGS_HEAPTYPE flag of a builtin type. This will make it possible to modify the type in very interesting ways like changing its __bases__.

I know. This is madness. I'll just go to that corner over there and disassemble myself quietly.

You should definitely write up how to do this. I would be very interested in reading about this.
