There is a new version of SRFI 113, Sets and Bags, at my staging site:
<http://www.ccil.org/~cowan/temp/srfi-113.html>.  This implements some
of the corrections from the Last^3 call that for whatever reason didn't
make it in to the last published version, notably the exclusion of
Cartesian product and powerset.

When that is posted, I'd like to go ahead and finalize, unless there are
cogent and urgent exceptions.
