SRFI 231 has been greatly expanded and polished from SRFI 179, adding a number of routines motivated by array routines in NumPy, and both empty and zero-dimensional arrays. The SRFI document is here: https://srfi.schemers.org/srfi-231/ Comments are requested on the mail list before June 24, although it you have something to say and can't comment before then, shoot a short note to the mail list and we'll wait for your comments.
