cons

   [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.
