Unfortunately I don't think we can come up with a partial order of all
the issues, and we will have to discuss things together (for example
separation in libraries and module system, and probably macro system).
Moreover, we need to discuss more-or-less unrelated issues in parallel
to finish the design of R6RS in a reasonable time.

Let's discuss that when the technical discussions start (we should
first collect the set of issues we want to address so that we can plan
