Hi Yakov, I gave a quick look at you project, the idea is really interesting but as you said it's really a PoC; I can think of an high number of issues. So I'm happy that our projects don't 'overlap' :) Can we really call your approach introspection? you are parsing the source files :/ Should not introspection be at run-time by definition? > > I made some PoC, and can generate bindings for Python and JS - > elev8.
