    Looking over page 68 of CLtL, I have a question about
    DEFVAR:

	From the description, it seems the (DEFVAR <variable>) should
	never give <variable> any sort of value.  It should simply
	"proclaim <variable> to be special and may perform other
	 system-dependent \bookkeeping-actions/."  Giving <variable>
	a default value seems like more than simple bookkeeping.

	Is this a reasonable interpretation?
Yes.
