I've now added seven commits on the way to implementing, testing, and
documenting the treatment of empty and zero-dimensional arrays in SRFI
231, which you can find here:

https://github.com/gambiteer/srfi-231/tree/weird-domains

I've added a checklist file weird-domains.html to keep track of changes
made (and not yet made).  As the old documentation joke goes, I'm sure
this list is incomplet and inkorrect, but it has proven useful as a guide.

I invite people to survey my changes to see whether they agree with
whatever decisions I may have made about semantics, argument lists, etc.
  I also invite proposed changes to code and documentation.

My guess is that we're at least halfway there.
