I've just published draft #2 of SRFI 163.  It was submitted by Per
Bothner, author of the SRFI.

  <https://srfi.schemers.org/srfi-163/>

Here are Per's comments on the draft:

  Except for some tag cleanup, the "real" changes are getting rid
  of "(i.e. vector)" plus adding a link to SRFI 164.

Here's the diff:
