Review Comment:
   It is better to directly compare with `==`, but if I really address as an 
`int`, then
   
   ```
   int(ffi.cast("intptr_t", p))
   ```

> SWIG is fine but we're not using it for anything other than exporting all of 
> proton-c's API as is.
> Unfortunately SWIG only generates CPython extension bindings. This may be a 
> problem on PyPy where CPython extensions are either slow or simply won't 
> compile.
> Unlike SWIG, CFFI is portable both on CPython and PyPy.
> It also satisfies the same requirements as SWIG currently does.
> In addition, calls to CFFI simply release the GIL which will help 
> parallelizing Python applications using threads.
> By using CFFI we can also get rid of all of our setup.py code and simply use 
> it to build the extension. We will also no longer have problems building 
> wheels.
> The newest version of CFFI supports pkg-config so we can use that to find 
> proton-c easily.
> I'm willing to help with the refactor but I'll need a mentor since I'm not 
> familiar with the code base.
