Ellipsis in the _pattern_



Since with this SRFI it becomes possible to put literal ellipsis in the
_template_, it seems like it would be useful to also be able to match
literal ellipsis in the _pattern_, while still being able to use ellipsis
to match multiple inputs.  However, I cannot think of a nice and concise
way to do this: enabling literal ellipsis to be present in the literal
identifier list would prohibit the macro from using ellipsis to match
multiple inputs.  Any comments on this idea, and how to go about it?
