True, the point is, that with #:rest, that is a keyword, I'd could
resort to the -keyword-style switch, which allows me to use
:rest or rest: (which I'd prefer for my personal taste), both
of which (including &rest as you suggest) would be standard
scheme identifiers, hence tollerated by being read as normal symbols
and therefore easily macro-expanded away.
