    [No comments on clos, but ...]

	Note that Common Lisp specifies for DEFVAR the same style of behavior.
	That is, re-evaluation of a DEFVAR with a new initializer is not
	supposed to modify the variable's value, but Symbolics' implementation
	does so anyway (and thankfully so, in my opinion), albeit with a
	warning.

    Actually, under normal circumstances (regular load, compile, etc), it
    does not.  But, if you INSIST (ie. c-sh-c in zwei with the cursor ON the
    defvar) it will comply. That, indeed, IS a nice feature.

Or if you do it in a patch.  Thanks for the implicit suggestion.
