[KLOTZ: defstruct initialization in :constructor ]

[Jonathan A Rees <JAR@AI.AI.MIT.EDU>]

Parameter lists for :CONSTRUCTOR's should act as much as possible like
lambda lists.  CLtL doesn't require this, but it seems like a good idea.

(DEFSTRUCT (STATIC-VARIABLE-CACHE-ENTRY
	     (:CONSTRUCTOR MAKE-STATIC-VARIABLE-CACHE-ENTRY
		(REAL-OBJECT &AUX
			     (VARIABLE (CAR REAL-OBJECT))
			     (UNIQUE-IDENTIFIER (CADR REAL-OBJECT)))))
  VARIABLE
  UNIQUE-IDENTIFIER
  REAL-OBJECT)

The silver book doesn't explicitly say that the &aux's can depend on the
real args, but it does say that &aux was included to make all desirable
behaviors possible, and &aux forms in lambda can depend on the args.
