-;;; FIXME: Setting *PACKAGE* to a non-PACKAGE value (even a plausible
-;;; one, like :CL-USER) makes the system fairly unusable, without
-;;; generating useful diagnostics. Is it possible to handle this
-;;; situation more gracefully by replacing references to *PACKAGE*
-;;; with references to (DEFAULT-PACKAGE) and implementing
-;;; DEFAULT-PACKAGE so that it checks for the PACKAGEness of *PACKAGE*
-;;; and helps the user to fix any problem (perhaps going through
-;;; CERROR)?
-;;; Error: An attempt was made to use the *PACKAGE* variable when it was
-;;; bound to the illegal (non-PACKAGE) value ~S. This is
-;;; forbidden by the ANSI specification and could have made
-;;; the system very confused. The *PACKAGE* variable has been
-;;; temporarily reset to #<PACKAGE "COMMON-LISP-USER">. How
-;;; would you like to proceed?
-;;; NAMED Set *PACKAGE* to ~S (which is the package which is
-;;; named by the old illegal ~S value of *PACKAGE*, and
-;;; is thus very likely the intended value) and continue
-;;; without signalling an error.
-;;; ERROR Leave *PACKAGE* set to #<PACKAGE "COMMON-LISP-USER">
-;;; and signal PACKAGE-ERROR to the code which tried to
-;;; use the old illegal value of *PACKAGE*.
-;;; CONTINUE Leave *PACKAGE* set to #<PACKAGE "COMMON-LISP-USER">
