TXR is a new Lisp dialect (project started in 2009) with real conses, car and cdr. Plus some little embellishments in that area:

  This is the TXR Lisp interactive listener of TXR 188.
  Quit with :quit or Ctrl-D on empty line. Ctrl-X ? for cheatsheet.
  1> (defstruct kar nil
       kar kdr
       (:method car (me) me.kar)
       (:method cdr (me) me.kdr))
  #<struct-type kar>
  2> (new kar kar 1 kdr 2)
  #S(kar kar 1 kdr 2)
  3> (car *2)
  1
  4> (cdr *2)
  2

:)

TXR Lisp has the cadr accessors down to depth five (caar to cddddr).

This stuff is not "muck" to be jettisoned; it is part of the essence without which we don't have Lisp.
