CxR Library

The (scheme cxr) library exports twenty-four procedures which are the compositions of from three to four car and cdr operations. For example caddar is defined by:

(define caddar
  (lambda (x) (car (cdr (cdr (car x))))))

The procedures car and cdr themselves and the four two-level compositions are included in the base library.

For more information see the R⁷RS Scheme Specification.
