It looks like ctypes albeit with a smaller API. (C definitions as text 
strings instead of Python objects.)

Sometimes I think Python and a ffi would always suffice. But in practice 
Cython's __dealloc__ can be indispensible, as opposed to a Python 
__del__ method which can be unreliable. And Python's module loader 
mostly takes care of the common problem of DLL hell.

With a ffi like ctypes or cffi, we don't have the RAII-like cleanup that 
__dealloc__ provides, and loading the DLLs suffer from all the nastyness 
of DLL hell.
