Naming suggestions

[Vsevolod Dyomkin]

In rutilsx I have called generic access operator ? - see here:
https://github.com/vseloved/rutils/blob/master/contrib/generic.lisp
It allows the accessor code to stand up a bit, which I consider a good
property. It is also chainable.

Here's an example usage (totals, weights and timestamps here are
hash-tables of hash-tables):

(defmethod update1 ((model avg-perceptron) f class val)
  (with-slots (step timestamps weights totals) model
    (incf (? totals class f) (* (- step (? timestamps class f))
                                          (? weights class f)))
    (incf (? weights class f) val)
    (setf (? timestamps class f) step)))

AT also seems a decent choice
