Our views just differ in whether you think of a `setter' as already
including the above (undoubtedly necessary) "res-set" operation or not.
I understood "setter" as the term is used for (generalized) variables
like in gv.el.
What I meant is that just passing by value is not sufficient, you have
to set a symbol's value somewhere. With regard to that, no, this is not
different from `delete'.
Michael.
