Unless you really don't know the number of dimensions of your array in
advance, (apply #'aref array list) sounds to me like it's going to be
inefficient.  It's going to be particularly hard to produce good
compiled code for it.  I agree that apply is better than eval, but not
by that much.  At any rate, the inverse of aref in Allegro CL appears
to be excl::.inv-s-aref.  So you can probably do

  (apply #'excl::.inv-s-aref newvalue array subscript-list)

This will work until we get Franz to make (setf (apply #'aref ...
work.
