Oh that's very interresting, so in some way you *are* also decoupling ClojureScript backend from it's parse and analysis components ! But doing so in a separate project, and in a more ambitious form than what i proposed in my application.
Maybe there is a possibility of pairing the projects ? It would be nice to have David Nolen feedback about that. Anyway, i'm gonna spend some more time studying your CinC code, and i will probably get back to you with numerous questions :) If you have any comments or corrections that you'd think may be nice for the GSOC applications, i'd be very happy !
