This is an instance of a fairly general problem with Lisp's equality
tests (and it's not really specific to Lisp, admittedly).
Maybe a half-sane way to solve this problem is to provide a generic
"equality driver" which takes an argument specifying which objects to
compare for structural equality (i.e. where to keep recursing).
