The code is here, BTW:

One interesting feature is that they seem to support different backends.
There's apparently one for libffi and one for ctypes so far. Another one
based on Cython would be cool. Even the existing ffi backend implementation
would have looked better in Cython, it's currently some 3000 lines of C
code. And Cython could certainly benefit from an ffi backend itself for a
couple of tasks, this topic has come up before a couple of times.
