I noticed this contradiction, too... :) If we're not going to use c[ad]r composability, why not just use unique, easily distinguishable names for all of these that don't compose:

  car  --> hd
  cdr  --> tl
  caar --> inner
  cddr --> skip2
  cadr --> second
...or something like that. Unique names would reduce errors.
