I've just published draft #6 of SRFI 140.  It was submitted
by Per Bothner, author of the SRFI.

  <https://srfi.schemers.org/srfi-140/>

Here are Per's comments on this draft:

  This isn't quite ready for "last call" but it is awfully
  close.  The main blocker now is merging the Kawa invoke
  branch (which contains all the srfi-140 work) into the
  Kawa trunk.

  All of the procedures are now implemented.  There is now a
  testsuite (converted from the srfi-134 testsuite), which I
  expect will pass 100% by the time I make the announcement.

Here's the diff:
