The name of the writer generic function is the list (setf lock-owner). This list is not a form to be evaluated; it is the name of the function—in
other words, it is the "function specifier."
I've never seen the term "function specifier" before, could someone please explain what this means in context with the text. Also, I've been searching the Hyperspec, and I haven't found any reference to "This list is not a form to be evaluated" in regards to the writer generic function which is generated by the :accessor slot option. Could someone assist on where I might find more information? Thanks.
