I just committed a lot of changes to my personal fork of srfi-122 at

https://github.com/gambiteer/srfi-122

Most of these were in direct response to comments people made.

Please scan these.  I tried to have a more-detailed-than-usual commit
message.

I'm hoping that if you've made specific suggestions in previous emails
that I have not addressed, I can fix them before generating another pull
request for the main repository.
