The moment of evaluation of the form within LOAD-TIME-VALUE is not
precisely specified. CLtL2 and dpANS are explicitly vague about this.

You should use one of the alternatives

     (let ((*package* '#,*package*)) ...)

or

(defparameter current-package-at-load-time *package*)
     (let ((*package* current-package-at-load-time)) ...)

Both work in CLISP. Since #, has been removed from ANSI CL, the second
alternative is probably the most portable one.
