I've taken a look at Python bridge for other languages, there're several: For Lua https://labix.org/lunatic-python
For ObjC https://pythonhosted.org/pyobjc/ For JS https://github.com/ipython/ipython/wiki/IPEP-26:-Full-Featured-python-js-object-bridge I'm glad that the idea is not just my imagination, it exists and there're something to read. I'll start this work after release Artanis-0.2.2. Best regards.
