  From  Jargon  File  (4.2.3,  23  NOV  2000)  [jargon]: 
 
  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

  cons 
 
  /konz/  or  /kons/  [LISP,  "construct"]  A  {Lisp}  function  which 
  takes  an  element  H  and  a  list  T  and  returns  a  new  list  whose 
  head  is  H  and  whose  tail  is  T. 
 
  In  {Lisp},  cons"  is  the  most  fundamental  operation  for 
  building  structures.  It  actually  takes  any  two  objects  and 
  returns  a  "{dotted-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  tree}s  of  any  shape 
  and  complexity.
