the lingua franca beeing C, this extended C-api could be the basis for
bindings other than the python-ctypes ones.
every language out there has some kind FFI based on C.

I considered using the C++ API and the CPython one, but it felt like
work duplication wrt doing the same, extending directly libclang.
now, granted that some automation could be leveraged (swig,
gccxml+whatever) but that's an external dependency which I feel is
unnecessary.

cheers,
sebastien.
