I've just published draft #2 of SRFI 156.  It was submitted
by Panicz Maciej Godek, author of the SRFI.

  <https://srfi.schemers.org/srfi-156/>

Here are the author's comments on the draft:

  I've shortened the abstract a little bit, rearranged some
  sections and swapped a reference implementation accorting
  to the suggestions by John Cowan and Marc
  Nieper-Wisskirchen (cf the discussion on the mailing
  list).

  In particular, multiple instances of the underscore symbol
  are now allowed, where each occurrence stands for a
  separate argument. Also, there is no limitation with
  regard to the place where the underscore can be used.
