/*** List 
    is `Iterable`

    Different than Python:

    - append: `push`
    - extend: `add`
    - count: `len`
    - index: `find`
    - insert: `put`
    - remove: `del`

    Same as Python:

    - `pop`
    - `sort`
    - `reverse`

        a matter of idealism.  Ideally the semantic group
        of `start`, `stop`, `pause`, `resume`,
        and `run` are all temporal verbs, whereas the
        semantic group `begins`, `ends`, `first`,
        `last`, and such all apply to the state of
        spatial segments or lists.

        In Python, this function is called ``endsWith``.
        See ``startsWith`` for the rationale.
