The D Common Lisp library exists to enable using doubly-linked lists in a program using a style which resembles singly-linked lists as closely as reasonable. The fundamental unit of this library is CONS, containing a CBR, CAR, and CDR; this scheme very pleasantly uses the first four letters of the alphabet, and CBR can be thought of as having a backwards mnemonic.

Here is the page dedicated to this program.
