+;;; In sbcl-1.0.9, a condition derived from CL:STREAM-ERROR (or
+;;; CL:READER-ERROR or or CL:PARSE-ERROR) didn't inherit a usable
+;;; PRINT-OBJECT method --- the PRINT-OBJECT code implicitly assumed
+;;; that CL:STREAM-ERROR was like a SIMPLE-CONDITION, with args and
+;;; format control, which seems to be a preANSIism.
+;;;
+;;; (The spec for DEFINE-CONDITION says that if :REPORT is not
+;;; supplied, "information about how to report this type of condition
+;;; is inherited from the PARENT-TYPE." The spec doesn't explicitly
+;;; forbid the inherited printer from trying to read slots which
+;;; aren't portably specified for the condition, but it doesn't seem
+;;; reasonable for the inherited printer to do so. It does seem
+;;; reasonable for app code to derive a new condition from
+;;; CL:READER-ERROR (perhaps for an error in a readmacro) or
+;;; CL:PARSE-ERROR (perhaps for an error in an operator
+;;; READ-MY-FAVORITE-DATA-STRUCTURE) or CL:STREAM-ERROR (dunno why
+;;; offhand, but perhaps for some Gray-stream-ish reason), not define
+;;; a :REPORT method for its new condition, and expect to inherit from
+;;; the application's printer all the cruft required for describing
+;;; the location of the error in the input.)
