    How can I define data structures that are pairs using defstruct?
    How can I define data structures that contain pairs? What I want
    to say is:

    (defstruct (name (:type cons)) a b)

Believe it or not, there are some things you just can't do in Common
Lisp; this is one of them.  Generally, if CLTL doesn't say that you
can do a thing, then it is not possible.
