Chapter 3 of SICPy says plain "list" 88 times where it means a pair-based linked list, while chapter 2 consistently says "linked list" (and uses llist only as the function name). In the Python edition, "list" reads as a Python list, which chapter 3 never uses: its queues, tables, agenda and constraint networks are all built from pair/set_head/set_tail, and even the mutex's "one-element list" is llist(False).

Section	Changes
