Lisp code in those days was written to avoid unnecessary allocation.
You'd use imperative-style RPLACA/RPLACD (aka setcar/setcdr) a lot,
nreverse, nconc, that sort of thing.  All not really in the Lisp spirit,
I would say, but it reflected Lisp programming practices from even
earlier and more limited machines.
