Likely so.

I chose swig after reviewing the options listed here, and I didn't see cython on the list:

http://docs.scipy.org/doc/numpy/user/c-info.python-as-glue.html

I guess that's because cython is different language, right?  So, if I want to interactively call C++ functions from say ipython, then is cython really an option?
