I've just published draft #2 of SRFI 151.  It was submitted
by John Cowan, author of the SRFI.

  <https://srfi.schemers.org/srfi-151/>

Many of the changes were made in response to discussion
here:

Here are John's comments on this draft:

  [This is...] the end of my work on SRFI 151, even though
  it is too soon for last call.

  Of course, if people find bugs, that's different.

Here's the diff:
