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 <https://srfi.schemers.org/srfi-149/>.
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.
Regards,
SRFI Editor
