Actually there's a similar mechanism in Python with the ctypes module: https://docs.python.org/3/library/ctypes.html I had used it a bit. For example in https://trac.osgeo.org/gdal/browser/trunk/autotest/gcore/testnonboundtoswig.py#L166 Downside of this approach is that if you could get the function prototype wrong and a runtime crash, as there's no checking against the .h files.
