What I would like to see if some kind of extensibility in the syntax.
Perhaps using methods.  I have often seen projects using `eval' just
because the options they are setting are not trivial assignments, but
conventional modifications like prepending an item to a list or setting
a symbol property (check out the .dir-locals.el for Guix if you want to
see a massive "Do you want to accept all these variables" prompt).
