Another item that needs a clarification and I don't see it listed in the page is the one discussed in https://trac.clozure.com/ccl/ticket/1389 and https://trac.clozure.com/ccl/ticket/1082
Spec is not explicit, and currently different implementations do
different things.
TL; DR:
(let ((*print-circle* t)
(name "q"))
(format nil "~A ~A" name name)) ==> ?
