No, this is the way it's supposed to work --- SORT destructively
modifies its argument, and it is used for its result.  If you want
q to be bound to the sorted list, you need to do something like:
     (setf q (sort q #'<))

Notice that since SORT is a function not a macro, it would be
difficult for it to have the effect you were expecting.  q gets
evaluated before SORT even "sees it", and so the function is
applied to the list that q was bound to, not the symbol q
itself.
