Bradley J. Lucier, author of SRFI 122, Nonempty Intervals and Generalized Arrays, has asked me to announce "last call" for this SRFI. He believes that it is ready for finalization, but would like to give reviewers one last chance to submit corrections and feedback before we finalize it. (Note that there was an earlier last call in late September, but there have been enough changes since then that we're doing one more.)
If you're interested in this SRFI, please give your feedback via the SRFI 122 mailing list before 12/7/2016. After that, assuming that no major revisions are required, we will declare it final.
Regards,
SRFI Editor
