Actually, this is wrong. C-h f gv-define-setter says:
The first arg in ARGLIST (the one that receives VAL) receives an
expression which can do arbitrary things, whereas the other arguments
are all guaranteed to be pure and copyable.
So using ,v twice will cause havoc in things like
(setf (window-buffer foo) (pop buffer))
