+@c FIXME? Not sure what or how much to say about these.
+@c See cl.texi for an example of using gv-letplace.
+For more control over the expansion, see the macro @code{gv-define-expander}.
+The macro @code{gv-letplace} can be useful in defining macros that
+perform similarly to @code{setf}; for example, the @code{incf} macro
+of Common Lisp. Consult the source file @file{gv.el} for more details.
