John Cowan, author of SRFI 143, Fixnums, 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.

<https://srfi.schemers.org/srfi-143>

In particular, I appeal to anyone reading this to try the
sample implementation, run the tests, and send feedback
about your results.

If you're interested in this SRFI, please give your feedback
via the SRFI 143 mailing list before 2017/5/22.  After that,
assuming that no major revisions are required, we will
declare it final.

Regards,

SRFI Editor
