Thanks for sharing this. One problem with SWIG is that the final
bingings are very bloated - there is the .so module and then there is
a python module on top of that. And classes are emulated in that
python module. Cython, on the other hand, creates just one nice C
file, which you compile to .so and that's it. So it's much faster and
very easy to debug - you just look into the generated C file to see
what's really happening (it's very readable).
Is there some example of your finite element code? I'd like to look at
that how you use instant in there.
