I've just published draft #3 of SRFI 158.  It was submitted by

John Cowan, co-author of the SRFI.

Here are John's comments on the draft:

  This is the third last call for SRFI 158.  There is one new

  procedure,, bytevector-accumulator!.  All the editorial corrections

  have been included as noted on the mailing list.

Here's the diff:
