I've just published draft #3 of SRFI 160.  It was submitted by
John Cowan, author of the SRFI.

  <https://srfi.schemers.org/srfi-160/>

Here are John's comments on the draft:

  I've decided that some of the procedures I imported from SRFI
  152 for the last draft really only make sense on u8vectors, so I
  have removed them from this SRFI.  Instead, there will be a
  future SRFI that allows treating bytevectors as if they were
  strings of ASCII characters, a la Python 3 bytes objects.

Here's the diff:
