I've just published draft #3 of SRFI 169.  It was
submitted by Lassi Kortela, author of the SRFI.

  <https://srfi.schemers.org/srfi-169/>

Here are Lassi's comments on the draft:

  Just like the last draft, there are no material
  technical changes, just more clarification and
  examples. By request, there's now a formal
  grammar extension to standard Scheme.

Note that this SRFI is still in its last-call
period.  Lassi asked me to keep the deadline
unchanged from 25 July.  Thank you for your
feedback!

Here's the diff:
