How do you feel about using Python generating code just like Vala code is generated? Doesn't GObject basically mean all the languages supported are compatible and we can write libraries/applications (which are generated into C code) and they are binary compatible with each other without extra code or configuration. I think that's really interesting and could make very fast, and robust applications very flexible as well. I am actually watching a talk on PyGObject by the author Tal Liron. https://www.youtube.com/watch?v=6QrGmA_RR4E https://www.youtube.com/watch?v=6QrGmA_RR4E
