Actually I was thinking about the bjam rewrite: If you redesign it, I
would strongly suggest to keep a clean separation between frontend and
backend in mind, precisely to make it possible to have different
frontends (and different languages etc), all using the same support for
dependency tracking and all the other core bits.

Having a "python frontend" still pass things to the bjam builtin parser
sounds strange and inefficient (but likely I just don't understand how
this would work).
