Final SRFI 149: Basic Syntax-rules Template Extensions Arthur A. Gleckler 08 Jul 2017 17:01 UTC

Scheme Request for Implementation 149,
"Basic Syntax-rules Template Extensions,"
by Marc Nieper-Wißkirchen,
has gone into "final" status.

The document and an archive of the discussion are available
at <>.

Here's the abstract:

  The rules for valid <template>s of <syntax rules> are
  slightly softened to allow for more than one consecutive
  <ellipsis> in subtemplates, and to allow pattern variables
  in subtemplates to be followed by more instances of the
  identifier <ellipsis> than they are followed in the
  subpattern in which they occur.
