commit 1a6a4d55701aaa199c14e1ef1ee1b6455922d761

    Unit test for add_event_listener() example
    
    Adding a unit test for the pydoc example in add_event_listener(). I really,
    really don't like how the tests for these documentation examples are turning
    out. The end result looks precious little like the example and is convoluted as
    hell.
    
    We should revisit how we do documentation example testing in the future, but
    that'll be a subproject in itself.
