Scheme Request for Implementation 169,
"Underscores in Numbers,"
by Lassi Kortela,
has gone into "final" status.

The document and an archive of the discussion are
available at
<https://srfi.schemers.org/srfi-169/>.

Here's the abstract:

  Many people find that large numbers are easier
  to read when the digits are broken into small
  groups.  For example, the number 1582439 might
  be easier to read if written as 1 582 439.  This
  applies to source code as it does to other
  writing.  We propose an extension of Scheme
  syntax to allow the underscore as a digit
  separator in numerical constants.

Many thanks to the author and to everyone who
contributed to the discussion of this SRFI.
