As an alternative to #7, SRFI-46 proposed allowing an optional ellipse specified as an identifier before the literals list in syntax-rules:
(syntax-rules ::: () <ellipse now represented as ::: instead of ...>)
Do we allow this, and if so how does it interact with the escapes from #7?
To be revoted because there was no simple majority.
Added.
The WG voted to accept this feature.
