:cons: /konz/ or /kons/ [from LISP] 1. vt. To add a new element
to a specified list, esp. at the top. "OK, cons picking a
replacement for the console TTY onto the agenda." 2. `cons up':
vt. To synthesize from smaller pieces: "to cons up an example".

In LISP itself, `cons' is the most fundamental operation for
building structures. It takes any two objects and returns a
`dot-pair' or two-branched tree with one object hanging from each
branch. Because the result of a cons is an object, it can be used
to build binary trees of any shape and complexity. Hackers think
of it as a sort of universal constructor, and that is where the
jargon meanings spring from.

ALL USERS PLEASE NOTE ======================== CAR and CDR now return extra values.
The function CAR now returns two values. Since it has to go to the trouble to figure out if the object is carcdr-able anyway, we figured you might as well get both halves at once....
