I've just published draft #3 of SRFI 140.  It was submitted
by Per Bothner, the author of SRFI 140.

  <http://srfi.schemers.org/srfi-140/>

Here's the diff:

  <https://github.com/scheme-requests-for-implementation/srfi-140/commit/524bbd11c8179b5bf3177030bcf3a685e1d2fa18>

Here are Per's comments:

  There are two tweaks, both coming from Jim Rees:

  (1) Fix an example to use char? rather than character?

  (2) Specify that number->string and get-output-string (and
  symbol->string) all return istring.

SRFI Editor
