First, I strongly disagree with voting here for reasons that I hope others will elaborate on. Second, I think that squeezing all possible language bindings into a project is also unproductive. What is it that the webkit people did for this? I think they had gobject bindings, and then all of the languages have their own gobject bridge to take advantage of that. Naturally the downside here is that gobject means you have a gtk dependency. A similar solution would be interesting and worth exploring, though, especially if something similar without gtk exists.
