Interface to the C linked list type.

Discussion

List is a complete package of functions to deal with singly linked lists of pointers or integers.

Features:

  1. Uses mem package.
  2. Has loop-back tests.
  3. Each item in the list can have multiple predecessors, enabling different lists to 'share' a common tail.
