Marc Nieper-Wißkirchen, author of SRFI 155, Promises, 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-155>

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 155 mailing list before 2018/9/14.  After that, assuming
that no major revisions are required, we will declare it final.

Since this SRFI is closely tied with SRFI 154, we're extending the
last call for SRFI 154 to the same date.

Regards,


SRFI Editor
