I've just published draft #8 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:

  I did another read-through, and found a few changes to
  make.  I don't know how you want to do it - maybe another
  last call with a shorter dead-line?

Here's the diff:

  <https://github.com/scheme-requests-for-implementation/srfi-140/compare/3bd13ca71b1790c988decf5e280d05367a763132...0b8e34a62813ba5c725c0d87708f41b9ee1f3e06>

Because of these changes, I'm extending the last call
period.  Please send your feedback before 2017/5/24.

Regards,

SRFI Editor
