;;;; A package macro that expands into a call to itself and does not get
;;;; smaller. Not a ring -- the call is inside a quasiquote, so it is output --
;;;; and so it is bounded rather than refused, with the macro named at the call
;;;; site. The name in that message is the qualified one, because that is what
;;;; the importer wrote.
