Looks good to me.  This will take a little more time to implement and
test sufficiently.

I've opted to use integer bitmaps rather than bitvectors in the sample
implementation, to avoid the (rather large) SRFI 178 dependency.  This
should be extremely efficient for small sets, which probably describes
99% of the use-cases for enum-sets.

The remaining question: Shall we use syntax-case in the sample
implementation?
