I've implemented (c), so perhaps an (r6rs enums) library should be packaged along with it.  I think this closes out everything.  Arthur, can you send me the open threads?  After that's dealt with, we're ready for last call.

How would you suggest this work?  I was discussing the idea with John
on the #scheme Freenode channel and John suggested three possible
ways of combining SRFI 209 and (r6rs enums):

(a) Ensure that (r6rs enums) can be implemented on top of SRFI 209.

(b) Do the above and provide a sample SRFI-209-based implementation
of (r6rs enums).

(c) Add all of the (rnrs enums) forms to SRFI 209, making this a
proper superset.

(I'm paraphrasing, so apologies to John if I've misinterpreted

If it's possible (and I believe it is) to make this SRFI compatible
with the R6RS library without too much redesign, I'm all for it.
