I've just published draft #3 of SRFI 165.  It was submitted by
Marc Nieper-Wißkirchen, author of the SRFI.

  <https://srfi.schemers.org/srfi-165/>

Here are Marc's comments on the draft:

  - Remark that further details on the relationship to SRFI 166
  can be found there.
  - Specify that SRFI 165 has to be fully compatible to non-local
  control flow.
  - Add proper tail calls.

Here's the diff:
