Marc Nieper-Wißkirchen, author of SRFI 136, Extensible
record types, 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.

If you're interested in this SRFI, please give your feedback via the
SRFI 136 mailing list before 12/16/2016. After that, assuming that no
major revisions are required, we will declare it final.

Regards,

SRFI Editor
